okay well i bought my macbook air in november and i am getting really slow ssd speeds. Its the 11.6 inch model 1.4 ghz and 2 gb ram. i am getting

now i know these are slow but do you guys think apple would replace the ssd because of the slow speeds/or should they? thanks

If they determine that it's a problem, yes.

well its oubiously not a problem, i mean the computer is working. but i mean do i have anything to say to them? like have they advertised the ssd speeds or something like that? thanks

They won't advertise ssd speeds because the are all inconsistent and they depend on a lot of factors

Slow relative to what?

I don't think you're going to get very far with this.

Do you write to it a lot (as in massive volumes of data)? SSDs do slow down over time, but usually not this quickly. Digilloyd sells a "Disk Tester" application for $40 that supposedly reconditions an SSD. Also, if you can boot from a USB volume, you can run a secure erase of your SSD, which essentially resets it. That would require reinstalling everything, however.

If you are really concerned about it, download Carbon Copy Cloner or a similar application, back up your drive, and look into doing a secure erase. I've never done one, so I don't know how it's done.

wen some people are getting 210/250 and im getting 140/180.......thats not a small difference ...i wouldnt mind if my numbers where a little higher..but thats unacceptable. why should i get the inferior product when i paid the same amount of money?

Just curious, how do you know what write and read speed is?

Do you know there are different types of measurments? Obviously not.

For example, most people measure large file transfers (faster), but real life small file transfers are slower.

Read the OP :)

It says what the speeds are, not how he measured them.

Can someone explain how to do this? I've never done it before.

there are 2 different brands of SSD in the new airs one being faster than the other. looks like you got the slower one like most of us.

I bet a secure erase will bring it back up to spec anyway

How do we know that's not a trojan exploit for a mac that an unsuspecting person would run and give it a password... and BAM...wipe out their hard drives...

It's the website of the developer, which is a commercial producer of software. It isn't a bit torrent site.

Because its a well known software company and a well known testing tool.

ive done the secure erases. not helping. but hey i guess you get unlucky. i will probably just get an owc ssd. i just dont think its fair lol :rolleyes:

I understand how you feel here, as I have the "slower" unit as well. But keep in mind that these numbers mean very little in actual use. If you set 2 identical Air's side by side, one with the "slow" SSD and one with the "fast" one, I'll bet that without running a disk speed test you wouldn't be able to tell me which is which. With that in mind, does it really matter?

Exactly... my 13" MBA ultimate has the slower of the two SSD specs, but it is still 5x faster than my HDD equipped iMac.

I don't think Disk R/W performance is the bottleneck for your 11" MBA.

word you guys are right. now i kinda want a different ssd for my i5 imac...the intel x-25 is ehhhh...:(

Don't fall into the hype, I think you'll be dissappointed. I've used all types of SSD's ranging from Intel to Sandforce to Indellix. If I were to rate them Intel would be at the top of my list. In benchmarks, sandforce based drives may look superior, in actual usage they perform damn near identically and Intel has the advantage of rock solid reliability and support. The only problem with Intel SSD's at the moment is the 160gb capacity.

...as far as SSD's go, I have an intel G2 80Gb in my HP DM4, a Crucial m225 128Gb in my whitebook, a WD Scorpio Blue 64Gb in my Dell 8100 P4 ~11 year old desk top using a IDE to SATA converter and my 11" MBA Toshiba SSD and they all seem to be just about as fast as each other in day to day use = benchmarks don't mean squat and all the bottle necks aren't the SSD in any of these systems I'm running!

I think this slow down relates to no trim support in OSX.

Just do a Time Machine backup, secure erase the drive, reload the OS and allow the setup utility to pull your data fro your Time Machine backup. That will bring the disc back to its factory performance.

Not sure of this, pwolfe, because I've seen many opinions in this forum, but I was under the impression that under OSX trim support isn't necessary, and that this whole topic of SSD's "slowing down" is massively overstated. It's hard for me to believe that a machine this new (even assuming he received it on Day 1) is going to need this process to speed up an SSD.

This is the first Ive heard of the "slow" SSD and the "fast" SSD. I'm about to purchase a new MBA (not sure yet which size and specs), but how do I know which Im getting or is it a crap shoot?

There is a long current thread on the forums about this issue - I can't remember exactly, but I think they determined that it was very difficult to get a "fast" one - you actually have to boot the unit and look in the "About this Mac" menu for specific model numbers for the SSD.

The truth is that the speed difference is a bit academic, and really isn't noticeable in actual use, so my opinion is that it's not worth losing any sleep over.

Thanks RD but the sleep loss is a lost cause,lol, with my OCD , all these decisions and information overload has created a tech shopping zombie.

My main advice would be to stop obsessing about it, but if it remains in the 80-90 range longer term, then by all means take it in to Apple.

Just do a Time Machine backup, secure erase the drive, reload the OS and allow the setup utility to pull your data fro your Time Machine backup. That will bring the disc back to its factory performance.

Please, no secure erase and Time Machine restore. That's the worst thing you can do with an SSD drive. SSD drives are not hard disk drives. What you suggest would get rid of defragmentation, which is not much of a problem anyway, and is no problem at all for SSD drives.

The more you flap around and test it and benchmark it, the slower it gets. For best performance of an SSD drive, just leave it alone. Start "Activity Monitor", Select "Disk Activity", see what happens when you actually _use_ your computer, for example when you start an application. Have a look how many reads and writes operations per second you get, and how many megabyte per second.


My main advice would be to stop obsessing about it...

Best advice ever. And good SSD drives will improve the layout of the data on the disk if they have nothing better to do, so the more you benchmark them without interruption, the more the performance will go down.
