View Full Version : How fast is your SSD, and when did you buy your MacBook Air?

DeBilbao's recent review of the MacBook Air raised some interesting disk speed results. Specifically, he is getting read and write speeds about 12-20% faster than what the rest of us are seeing.

He downloaded Aja System Test (http://www.aja.com/products/software/) and ran the disk test with a 4GB file at the 1920x1080 and 10 bit video frame setting. Most of us are getting write speeds around 184 MB/s and read speeds of about 208 MB/s. He's getting 207 MB/s and 250 MB/s, respectively.

I'm wondering if Apple has made a running change to the MacBook Air (Rev D). I propose an informal survey. First, what are your read/write speeds running this same test? Second, when did you purchase your MacBook Air? Third, what is your Apple SSD revision number?


I'll start:

Read: 208 MB/s
Write: 184.3 MB/s

Purchased: November 2010

Revision: CJAA0201

Too lazy to check that but I think that's how you find it. As for benchmarking the SSD, use the AJA System Test linked in the first post.

Similar results for CJAA0201. January 2011 from MacMall.

Can we be more specific? :D 11.6" or 13"? 64, 128, or 256GB? SSD model? How much space used/left?

Yes, this is important. Larger capacity SSD models tend to be faster than smaller capacity ones. This could be why the speed is varying...

Actually, the capacity is pretty irrelevant. When it comes to HDs, that is true because bigger capacity means the drive is denser (assuming they are the same form factor), meaning that more data can be read or written each time the HD spins.

However, this does not apply to SSDs since they don't spin. 40GB SSD is as fast as 480GB one with the same controller. Amount of NANDs may affect the speed but usually they don't.

It shouldn't make too much of a difference, since I think each version uses the same number of channels, but in any case, I have a 256GB SSD with over 50% free right now.

Hmmm.. I'm starting to wonder if the SSD in newer MBAs is made by Samsung instead of Toshiba. In the past, Apple has used Samsung SSDs which were reported as "APPLE SSD SM128" in OS X. The new ones are SM128C now. It would make sense if SM stood for Samsung. Toshiba SSDs are "APPLE SSD TS128C" so again, it's logical if TS stands for Toshiba.

If I had to guess, the SSD in newer MBAs is Samsung 470-series as that has speeds of 250/220 MB/s, which makes sense when looking at the benchmarks. Apart from the speed differences, it looks like the newer ones support Native Command Queuing while older ones don't.

So it turns out I was sold an older revision, right? That's why it's slower, right? I'm mad!!! :mad::mad::mad:

Should I have asked the sales person to pull out the latest revision? Is it even possible to identify one? :(

Most likely no, unless you open it in-store to check the SSD model.

EDIT: Anyone with those newer SSDs willing to open the bottom cover to see is it a Samsung SSD? No need to take anything out, just remove the bottom cover and take a pic of the SSD, shouldn't void your warranty ;)

My Model btw is CJAA0201 and I do have a TS128C.

Sort of a letdown that there is such a marked difference in read/write considering the short timespan between them.

It could be. Perhaps someone running a newer MacBook Air could run Crystal Disk Info from within Windows to see if NCQ is supported? It isn't on the Toshiba drives.

In reality, those speeds are still considerably faster than a hard drive. It's a bit like the different screens that are out there. Sure there are some differences, but I doubt they will be particularly noticeable.

It may be a supply issue. That said, I'm a bit surprised that didn't turn up in the AnandTech review. The 11" Ultimate ought to have had the Samsung if you are correct.

However, this does not apply to SSDs since they don't spin. 40GB SSD is as fast as 480GB one with the same controller. Amount of NANDs may affect the speed but usually they don't.

This can be true for the most part if lower density nands are used instead of less nands.

ie the intel SSDs show this. the 160 is faster than the 80 which is faster than the 40, simply because they didn't fill the nand slots and left them empty. I'm not sure how the mba ones work, as I think the 256 would have more nand modules than the 128 and perhaps the 64, but we'd have to tear it open to see...

Then again the nand modules could be slower at higher capacities etc, so it is difficult to say for sure, unless we test.

So far it seem the AX ssds have higher read and write speeds than the CJ models.

But I'm actually curious about the random read and write 4k and such blocks. While numbers for continuous read and write are nice, the random read and write seem to contribute more to my day to day usage patterns. ie I have an intel 80gb x-25m G2, which read: 250mb/sec and write 70mb/sec advertised... and an OCZ agility 2 sandforce drive with read: 285mb/sec write 275mb/sec... in theory the sandforce SSD should blow away the intel drive. what I've actually seen is on the same computer, the intel drive boots faster, and gets a higher windows disk score (7.7) where the sandforce drive gets a 7.4 and boots about 1 second slower. Crystal disk benchmarks also show while the sequential speeds are faster on the sandforce drive, the intel drive is faster in random reads/writes. Don't get me wrong. the sandforce drive is still really fast, but I think that read/write numbers don't always mean much if we don't look at random small file read/writes.

Does any one have benchmarks for either CJ or AX ssds? My 128gb ultimate 11 inch uses the CJ ssd.

Also the native command queuing might play a role... here's something from wiki


NCQ is also used in newer solid-state drives where the drive encounters latency on the host, rather than the other way around. For example, Intel's X25-E Extreme solid-state drive uses NCQ to ensure that the drive has commands to process while the host system is busy processing CPU tasks. [3]

NCQ also enables the SSD controller to complete commands concurrently (or partly concurrently, for example using pipelines) where the internal organisation of the device enables such processing.

For example, the SandForce 1200[4] based OCZ Vertex II 50GB drive running on a Dell Perc 5i (which doesn't support SATA NCQ) delivers about 7,000 4k IOPS (50% write) at a controller queue depth of 32 IOs. Moving the drive to the similar Dell Perc 6i increases this to over 14,000 IOPS on the same basis

According to Intel, the read speed is the same for all, 250MB/s. 80GB has write speed of 80MB/s while higher capacities have write speed of 100MB/s. This is supported by AT's bench (http://www.anandtech.com/bench/Product/126?vs=125).

This (http://www.anandtech.com/bench/Product/195?vs=196) shows nearly no difference in sustained speeds between 40GB and 120GB SSD with the same controller.

FYI, 64GB and 128GB SSDs in MBA consist of four NANDs (4x16GB and 4x32GB) and the 256GB is made of eight 32GB NANDs.

The person didn't know why. But if I had to guess, I'd say that the most expensive models were the last in queue to get their SSD's revised, which should be happening soon (hopefully). But will I care at that point? Not really since my 14-day return policy will be long expired.

Thanks! The random IO read seems to be drastically different in the 40 vs 120gb comparison you linked to, and per my post I am rather curious about the random io performance rather than the sequential performance. I wonder if the 256 will show a higher random io vs 128 and 64 given the benchmarks you provided show a 3.5 fold random 4k read increase. Also I would like to see if the newer ssds are faster in this regard as well so I can feel thoroughly bad about not having the faster drive lol.

If those who paid more for their SSDs get the slower ones, it sucks. But that's mainly on a general principle, and will have no practical consequences. If it takes 2.5 seconds to open Photoshop instead of 2.0, I can live with that.

I bought my "ultimate MBA" yesterday from an official Mac reseller (location : Antwerp, Belgium) and have the 'faster' SSD (see my previous post). As the MBA is BTO and was in stock, I presume they already had it ordered a while ago. So I don't know why in the 'Big Apple' they're stating the ultimate MBA comes with slower SSD, while in a tiny country as Belgium, we get faster specs.

It's probably a function of production and inventory. Belgium might have just gotten a shipment, and the US-bound versions might get them updated later. Or perhaps FoxConn is just installing them indiscriminately as they run through their remaining inventory of Toshiba drives.

We have only a few data points, but some key observations seem to be emerging:
- There definitely appear to be some Samsung drives in new MacBook Air models, and not just the Toshiba drives mentioned in all the release reviews.
- The Samsung models appear faster and more advanced (NCQ support).
- The faster drives are more likely to show up in new 13" models with the 128GB SSD.
- 11" models generally appear to have the slower drives.
- One person has reported a 256GB SSD with the faster speed, but most of us have the slower drive regardless of when we bought it.
- A lot of people seem to be upset about the slower drive. Perhaps I shouldn't have brought this up. In any case, the Toshiba drive is still plenty fast. To me, it's like complaining about not having a Ferrari when you have a Porsche in the driveway.

Since Apple appears to be making running changes to the MacBook Air line, I wonder if they will make others? Might there be some subtle display changes, or even faster SSDs in the coming months? If so, does this indicate that the Rev D might have the shelf life of the Rev C, which also had some running SSD updates and went 15 months before giving way to the Rev D? NVIDIA did say they expected to be selling the 320m chipset for quite some time.

The problem is that there is no reliable way to detect when it was built. The old algorithms for determining the build date from the serial number no longer work since Apple changed them.

It's logical that people get upset. You can complain about getting a Porsche when you have paid the same as others that have got a Ferrari.

When you keep in touch with a forum like MacRumors, many times it happens that you discover a problem that you weren't aware of. That is one of these cases.

Other times you just discover a problem that you didn't notice and after this day you'll start suffering it. Didn't you noticed this yellow cast? Or the reduced battery life? or... whatever.

Although the new Samsung seems to be better, both drives are excellent performers, so why not just enjoy your MacBook Air?

If you paid for a Porsche and received one, you got what you paid for. If someone else got a Ferrari, good for them, but you didn't get scammed.

The gripe would be more legitimate if Apple had sent out review units with the faster drives, and then equipped shipping models with cheaper, slower drives. But in this case, it seems that some faster drives are trickling into the production line. I'm fine with that.

Talking about cars, if I had ordered a Porsche and got a Ferrari... I would complain for sure. The example is not that good for the case.

The gripe would be more legitimate if Apple had sent out review units with the faster drives, and then equipped shipping models with cheaper, slower drives.

In this case you can even file a legal complaint.

But in this case, it seems that some faster drives are trickling into the production line. I'm fine with that.

I'm fine too, and not only because I got the faster drive :cool: because when you buy something today, you always agree that the manufacturer can change the specs without pior notification.

IMO this sounds more like that you bought a Ferrari and you got a Ferrari but some buyers got a free Ferrari keychain on top of that.

If you put two MBAs next to each other, one with Toshiba SSD and one with Samsung SSD, I doubt you would notice any difference in everyday tasks.

What bothers me is that I had recently paid for something that I would have waited on had I known that a change would be taking place in a short amount of time. I am in the 6th day of my purchase and can return the product, but there's no way of knowing whether I would get one with a faster ssd. I could wait a month to buy another, but then again, I may get an older inventory. I don't feel like playing this game, but can't help but be annoyed that I paid the same premium for the "ultimate" version of the 11.6, but am getting a less then "ultimate" product. Many who get the ultimate versions of their products want the best performance that they can buy, and this information certainly goes against that goal. Frustrating......

I ordered mine on 9 jan and recieved it on the 20th of jan. Its the fast one starting with AM.

Spec:

1.86GHZ
128GB
4GB

It seems that if you buy a CTO then you will get the fasther one. So paying 100 dollars more for 2GB extra and a fast SSD is quite a good deal!

On the other hand, I live in The Netherlands. Seems like Europeans always get the faster one if CTO. But we also pay more then you do for an Apple.

But changes always happen, and it's rare than customers know when a company is going to make changes to a product line.

It's not like Apple advertised the SSD as being a certain speed or brand and it wasn't and now the new ones are actually up to advertised spec.

What's the alternative? That a company never improves its products without announcing a new model a few months in advance and then having zero sales while everyone waits?

I do understand that change happens, and was expecting a reply like this. It's just frustrating for me since I made the purchase less then a week ago, and feel that future models will have the faster. I am not however going to try to figure out when and where it will be put in the mainstream, and hope to get lucky when purchasing. Just venting I guess-prob gonna keep mine.

If not for deBilbao's excellent review, we wouldn't have known about this. Anyway, the increase in drive performance is nice, but nothing like the upgrade from the SSD in the Rev B to the "slower" Rev D drive (the Rev D specs about 3-4 times as fast in read and write speeds). Now that's noticeable.

On what basis? The product they sold you is as advertised. It isn't as if there is anything wrong with the Toshiba drive. Apple just is sourcing its drives from multiple suppliers, and some of them have faster controllers than others.

The only issue is that they would not be able to tell which is the faster model without opening it up and turning it on. I don't think the apple store would be willing to go through that, but I'm not sure. I was debating this, but again, I have the 11" and it doesn't seem to be showing up on them....yet

Hey all,
Spoke to apple care about my situation. They pretty much took everything I said down and told me to contact the apple store where I bought it about an exchange. Not sure if i'm going to drive from Philadelphia to delaware to do this, and then it might end up with the same drive. I think what might be happening is that as another member had said, apple is using different suppliers for the SSD rather then progressing to a new supplier. This seems evident with people getting the toshiba and having recent manufacturing dates. The faster ssd's seem to be limited to non-us countries (unless I missed a post of someone from the U.S. reporting it). Anyway, if it's just a random draw of receiving it, then there's no point of me trying to exchange it. However, if apple is switching completely to samsung, then it's different and I would more likely consider returning it and waiting out a new one. Anyone obtain any new info from apple directly on this?

Might as well use the 14 day policy to the max, i was originally hoping the new MBP would come out w/in the 14 day policy, but that seems unlikely with the sandy bridge problems.
I think i'm almost hooked on the MBA portability and may not even go to MBP if they come out soon, this is why i'd rather have the faster SSD than not.

It's all about numbers. Same thing if I buy a car that's 405hp and then someone comes out with one that's 415hp. Weight even goes out the window when spec-jockeying. I want "the good one".

The older Samsung SSDs were notorious for having slow initial performance (for an SSD) and massive performance degradation over time. Digilloyd sells an application (Disktester) that claims to "recondition" SSDs, though I have not tried it (it's $40). Before I sold my Rev B, I ran XBench and was getting numbers in the low 40s.

Feb 15, 2011, 03:50 PM
Not sure what to make of this but I tested a 13 MBA at the apple store in Colorado after downloading AJA. The 13 inch with 128GB SSD tested in the 30's for both read and write. Not sure with SSD manufacturer it was. I shared the result with one of the dudes that works there and they had some story about the amount of abuse the display models take. As a point of reference I also tested a 27 inch iMac i5 and got r/w in the low 50's (I just realized this wasn't an SSD so it's apples to oranges as they say). All of this gives me great pause. My late 2008 macbook unibody is running in the mid 50's with 6GB of ram. I definitely want to upgrade to either a iMac i7 Quad core or a MBA 13 ultimate if I can get the 200-250 speeds people are reporting but would be sorely disappointed if I ended up with a mild improvement from my 250GB 5400RPM stock harddrive from 2008.

Can someone help me distill down the data in this forum though?

1. Samsung SSD is preferred to the Toshiba right?

2. Regarding the revisions "A" is best and "D" is worst?

3. Is 128 better than 256? Is 11 inch better than 13 inch? I really want the 13 inch 256 but could live with something less if the speed was materially faster.

A lot of this seems like worrying about getting from 0 to 60 in car in 3.555 secs vs 3.550 secs. I'd be more concerned about the quality and longevity of the SSD manufactured by Toshiba vs Samsung.

Any help/input is greatly appreciated. Thanks---

**New MBA also has a tiny scratch on palm surface right out of the box!! Figures when I exchange I end up getting a little bad luck! haha I may just return this one in a few days because of the scratch, I plan on reselling whatever laptop I get in a year or so anyways and the lack of "mintness" really bugs me.

Hey epic, sorry for the bad luck. I would go to have it exchanged tonight (if you live near a store) and be done with it. If the next one has issues, I personally would give up and get my money back-these things aren't supposed to be so frustrating, and aluminum is a scratch/dent magnet. I held this mind set when I exchanged mine, and luckily there were no issues with the second one.

Rev D is the newest model (late 2010). Rev A is the original MacBook Air from January 2008.

The fastest SSDs in MacBook Airs are the Samsung drives in in the newest revision. The second fastest, and by far more common, are the Toshiba SSDs in the newest revision. Most likely, if you buy a new MacBook Air, it will have a Toshiba SSD. It's plenty fast as it is.

Note that Samsung and Toshiba have been supplying SSD drives to PC manufacturers for several years. Older MacBook Airs (from 2008-2009) used an older Samsung drive that was a lot slower than the drives used in the late-2010 models (whether from Samsung or Toshiba).

At what point does all of this comparison become irrelevant and silly?

I have the slower drive but it is 5 times faster than the hard drive in my Blackbook.

I think having 4GB of ram VS 2GB is going to have a much bigger impact on system performance. I guess someone could argue that having less ram actually makes the faster drive more of a necessity.

These test are peak speeds, not real life.

Most of your apps will never max the speed of the SSD and since the MacBook Airs only have USB 2, it won't be a concern when transferring data to another drive.

Someone please tell me a real app (not a speed benchmark app) that will max the disk but not the Core2Duo CPU?

The CPU cache, CPU speed and amount of ram will have a much more significant impact on performance than the difference between thses two SSDs.

Bingo---that's why i decided to go with a new MBP or iMac. I might upgrade my MB unibody to an SSD and a separate HD in the optical drive but at the end of the day I am bottlenecking doing HB conversions at the CPU level...none of this really matters except for boot times and maybe very fractionally on app start times.

Feb 20, 2011, 02:30 PM
Just to bring more realism to the discussion:

In regards to the settings that everyone is using in the AJA benchmark app:

Uncompressed 10 bit 1080 @ 29.97fps = 13GB per minute!!!!

Uncompressed 10 bit 1080 @ 23.98fps = 10.42GB per minute!!!

Therefore the 128GB SSD could not even edit 10 minutes of video with the drive completely empty.

It's nice to see the high speeds in the benchmark app but it does not represent any real world situation.

Honestly, I'm trying to think of an app that would be an exception but
99% of people will not notice any difference.

Of course it makes a HUGE difference how fast the drive is. Its silly to even ask.

Its not just how long it takes to move a giant file around. Thats the easiest way to come up with a benchmark.

A faster drive is faster at everything, especially thrashing around picking up little files spread all over the disk. That's hard to reliably test but very easy to observe.

The Macbook Air is very very fast, much faster than a Macbook Pro at launching practically any program, running most compiles, switching userids, performing anything with lots of disc I/O such as checking for updates etc. In my real world speed comparisons between my 2009 13" Macbook Pro and my 2010 11" Macbook Air, there are several cases where the Macbook Air was 10 TIMES faster than the Macbook Pro. Thats not a small difference. And certainly not because its 1.6ghz processor is faster than the MBP 2.26ghz processor.

In real world, the speed makes an enormous difference. If newer machines are 25% faster, that is very interesting and worth trying to investigate.

Exactly ^^^^^

@dmelgar

I stated that I am seeing a 5x increase between my machines SSD vs HDD.

The SSD's are great, and for most users it won't matter which one they get.

The benchmarks only show peak performance (sustained not random, read and write), which is not a real world situation. How often does an app write a single 4 GB file and how many MacBook Air users will be in this situation?

I'm all for the idea of improved specs but my point is:

People are talking about spending hours driving, or on the phone with Apple, to return their current MacBook Air, in hopes of receiving a faster one. Many people will never notice the difference in their daily activities. Even the slower SSD is such an improvement that these people would be content if they had not read this thread.

Max speed does not matter. What does matter is that you are getting what you pay for. There should be no faster "revision".

The bottom line is that we all did get what we paid for (even those of us with the "slower" drive). If Apple gets a good deal on some slightly faster Samsung drives and adds them into the mix, that's fine with me. It isn't like they shipped out a bunch of review units with faster drives and quietly snuck a slower drive into the production units.

I decided to return my 11" MBA, while I really liked the form factor over my 2.0Ghz nVidia 9400m whitebook (with m225 128Gb SSD) or my HP DM4 i5 14" laptop with 8Gb RAM and intel G2 x-25 SSD (only 4.2 lbs) so the MBA's main advantage was form factor/weight vs. my other 2 machines.

I just couldn't justify keeping the MBA right now with the fact that both my above laptops were faster/more powerful, larger SSD's (with maybe the execption of the slight GPU advantage of the 320m chipset) and working fine...

In one or two revisions, maybe I'll be lucky enough to be able to use my applecare to get a replacement for my whitebook as I have ~2 years left on my ac for it:p

If not, by that time I'll probably donate my whitebook to one of my family members and just buy a MBA 11" for my uses...

That's fairly typical of the Toshiba drives. As far as the disparity, it's primarily a matter of the controller used, and the priorities of the manufacturer. SandForce puts performance first, and their drives outperform both Toshiba and Samsung. That said, some Mac users have reported some issues with them.

So everyone seems to be coveting the AXM rev Samsung SSDs, but my question is, besides being faster in sequential Reads+writes what if they have more performance degradation over time as compared to the "slower" Toshiba SSDs (not saying the Toshibas are great in this respect, just in comparison to the Samsung)? The older Samsung SSDs in the older MBA's had this problem, hopefully Samsung improved things this generation.

Also, another thing we haven't compared is the random writes/reads as some have stated here.

That's the far more common version and nothing to be angry about. It's still a decent performer for a SATA II device. With the disruption in Japan, it's possible we'll see some more Samsung drives for a while, but the Toshiba still performs well out of the box and, more importantly, holds up to severe use.

I bought mine less than 2 weeks ago. It should be noted the correlation between this SSD change and when the Apple stores started carrying 4 gig RAM models. That is when/why I bought mine.

People who are saying that they just bought theirs and yet it has the Toshiba that probably means its been sitting in the back stock room since before they made this change.

I am not sure how Apple will/would respond to this because it is a pretty substantial difference. Its the difference in shaving a few seconds off functions, and that is similar to paying for the upgraded processor for example.

But I'm actually curious about the random read and write 4k and such blocks. While numbers for continuous read and write are nice, the random read and write seem to contribute more to my day to day usage patterns....

but I think that read/write numbers don't always mean much if we don't look at random small file read/writes.



the only post i've seen that makes any sense. most are just i'm upset mine is the slower drive blah blah blah. I can understand wanting a a faster drive, but will you see any difference?

what if the new drive writes slower randomly, so while you can obtain sustained higher sequential speeds, you'll be slower in many other tasks???

micro sd cards suffer the same issues. for example if you want to run android off a sd card you'll do much better looking into sandisk class 2 and 4 cards vs. any class 6, 8 or 10 cards. This is because random r/w is awful on the higher class cards vs. sandisk when running android of sd card. Yes, we don't run android but the same reasoning applies here.

personally, i'd want faster sequential r/w since i don't normally do large file transfers on my machine. When I do, a few extra seconds won't kill me. I'd like faster overall perf.

my 2 cents.

Nah, I'm just kidding. Lol, but anyways, I am trying to calibrate it, but I'm still killing the battery lol. Funny because if this was on my Windows laptop, I would've been able to kill the battery in 10-15 minutes tops by just browsing a few websites with some tabs open.

that's cuz your windows laptop was a pos. my thinkpad lasted just as long if not longer than my 13 ulti.

Ultimate MacBook Air 13 (bought yesterday):

180.9 / 207.7

Revision: CJAA0201

So it turns out I was sold an older revision, right? That's why it's slower, right? I'm mad!!! :mad::mad::mad:

Should I have asked the sales person to pull out the latest revision? Is it even possible to identify one? :(

Jeeze Louise,if this makes you mad, you are going to have to sell it, unless you can look past this "problem"

I dont think you will see major differences on the order of 2 seconds vs 2 miliseconds.

The question is...do you want the better spec'd drive and are you willing to make a return to get it. For me, I would return it (if within the 14 day return) for the better spec'd SSD.

So does the ssd only affect the download speed??? or does it affect overall system performance? like surfing the web for instance?

It theoretically affects anything that access disk. However no matter how much you try to time times with a stopwatch, you will never be able to measure the difference. It's too insignificant to worry about. Just enjoy your new Mac and don't worry about it. Even if you return this one, there is no guarantee that another one won't have the same brand SSD.

Not sure if this was mentioned before but according to Techreport the Samsung 470 doesn't have very good Garbage Collection. (source (http://techreport.com/articles.x/20087/5)). While the Kingston V+ (Toshiba controller) has very good GC (source: Anandtech).

So those with a TS SSD may not be unlucky after all.

Well if the garbage collection is indeed worse, I'm fine with the TSC. This should be mitigated by lion's trim but we'll see. Would rather have a longer lasting drive than 60mb/s at most improvement.

According to the Techreport review TRIM doesn't solve the issue on the Samsung 470.

Seems like something is off with it. Maybe Samsung has solved it with newer firmware.

I exchanged a bunch of emails with OWC tech support b/c it seemed that the heat pad was a bit too thick and this, in turn, caused the pad to press up against the inside of the bottom plate of the Air which, in turn, didn't allow the screws for the bottom plate to go back in nice and straight and flush. They went in, but with maybe half a mm sticking out on each of the three front screws. Tech support assured me that the heat padding was within spec, etc., etc. and that there would be no issues related to the padding pushing up against the inside of the bottom plate.

I didn't notice any bowing or anything of that sort. The chip installed fine...it's just when I tried to put the bottom cover back on is when I noticed the above "issues" (or "non-issues" if you believe OWC).

Anyway, everything works fine and I don't have any sleep issues at all. I'm just wondering if I should be getting faster read/write speeds?

I guess I'm just basing my question on what OWC puts on the Specs page for the SSD:

"Performance
Sequential Read (up to)285MB/s
Sequential Write (up to)275MB/s"

I know it says "up to" but I'm wondering what factors would make it less than their quoted speeds.

Those speeds will only be reached with 0 fill data.

In case you have bootcamp on your machine try running ATTO disk benchmark. It runs with 0 fill data.

I have no idea what its read-write numbers are and don't really care. All I know is that it swaps data to and from memory exponentially faster than any mechanical drive I have ever seen.

DeBilbao's recent review of the MacBook Air raised some interesting disk speed results. Specifically, he is getting read and write speeds about 12-20% faster than what the rest of us are seeing.

He downloaded Aja System Test (http://www.aja.com/products/software/) and ran the disk test with a 4GB file at the 1920x1080 and 10 bit video frame setting. Most of us are getting write speeds around 184 MB/s and read speeds of about 208 MB/s. He's getting 207 MB/s and 250 MB/s, respectively.

I'm wondering if Apple has made a running change to the MacBook Air (Rev D). I propose an informal survey. First, what are your read/write speeds running this same test? Second, when did you purchase your MacBook Air? Third, what is your Apple SSD revision number?


I'll start:

Read: 208 MB/s
Write: 184.3 MB/s

Purchased: November 2010

I got my MBA ultimate 13" last week, thought of chiming in reporting the drive used.

Surprised! I got the old Toshiba instead.

If you guys actually use programs like coconutbattery, you can see how old is your machine. Although I just got it last week, but the age of my MBA is 22 weeks (!) old. Not sure how they actually got a machine as old as 5 months sitting around in their warehouse. Though, the battery is absolutely fresh with 0 cycle.

It was really heart sunken when I found out it's slower driver, as I'll be using it to stream lots of samples for audio works. However, 200MB isn't slow either, and the Samsung SSD seems to suffer and performance drop after using it for some time (I assumed it's write speed but not reading speed?), so hopefully it can handle whatever I throw on it...perhaps going to upgrade it to a larger SSD e.g. OWC series when the price dropped to an affordable price range. :o

I'll be putting lots of strains on the SSD with lots of audio samples clusters streaming from the SSD, and that's why I'm concern.

Though, I'm reading good thing about the machine on audio usage, and I think it was dated back earlier this year, so I guess I'm fine.

In the end, I don't think Apple will make such sudden decisions going from toshiba to samsung, and then samsung back to toshiba. Reading krimp also got a toshiba drive, it seems that Apple decided to put the toshiba back on the MBA. I think Apple has a good reason why they put back the initial toshiba on. Perhaps it's because of the lack of performance on TRIM of the samsung chips/controllers even under Lion?

I'm counting Apple on this.

Use AJA system test, or browse few pages back on this thread, there're a few testing application mentioned. I don't think you should be bothered to do the test, test results should be consistent across all toshiba SSD.

Just chiming in here, no idea when my 2011 13" MBA Base was built, but it has the Toshiba 128GB drive in it based on the System Profiler. I didn't bother to bench it, what would be the point! I could really care less if my SSD can read at 200 or 250 and write at 180 or 210. It is still faster than the SSD that came in my Early 2011 MBP and blows away any mechanical hard drive.
