How fast is your SSD, and when did you buy your MacBook Air?

Garbage Collection???



btw thanks for the reply bcaslis

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.

How well does it fit? I've heard some people talk about the bottom bowing out with the OWC SSD. How about sleep issues? Does it sleep OK or have any other issues?

No issues with either of mine, they fit perfectly!

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?

Thanks for the feedback. Your speeds match the Samsung SSD so they sound reasonably fast to me.

Which size SSD did you install?

 

[pinkoos]

Thanks for the feedback. Your speeds match the Samsung SSD so they sound reasonably fast to me.

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.

Ah, okay. Didn't realize that. Guess I'm not as "techie" as I thought I was!

I have Windows XP running within Parallels. Will that work?

Parallels probably won't work. But it can't hurt to try.

Just found this thread so my post is late. I got an early 13 inch MBA Ultimate last October. In has a Toshiba TS256C 256GB flash drive. 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.

Just bought the new MBA 13" from Bestbuy and it has the new Samsung SSD.

I just ordered one today online. Will be interested to see what i get, I'm in Thailand so i gather it will ship from China? will be pot luck i think..


Just saw the shipping details its being sent from China, do they make them all there now?

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

Same as you. Bought at the same time.

 

[harleymhs]

Im sure ALL the NEW MBA have the faster SSD in them... 3 people in my office have older ones and they have the Toshiba .. Mine is one month old and I have the Samsung.. Im sure you guys that ordered yesterday will get the the Samsung... Keep us posted on what you get..

Or the new MBA could have a SSD that trumps the current one by a factor of 2.

Im wondering if my terrible scores have anything to do with the fact that the TRIM on OSX 10.6.8 that I recently updated to is trying to do its best to make up for the past 6 months of non TRIM performance and making it worse somehow?

From what i've read in the lion forum, the gm atleast doesnt support trim for 3rd party ssd manufacturers, pretty greedy thing to do if they dont fix that
