    Just got a mid-2013 Macbook Air 11" from the refurb store today. It has a 256GB SSD labeled "Apple SSD TS0256F." I assume that means Toshiba. Based on reviews and reading the forums, I was expecting write/read speeds of ~700/700. But BlackMagic is showing more like 500/600 for this Toshiba drive.

    Anybody else have a Toshiba SSD in a mid-2013 Air? Doesn't seem to be the norm as far as I can tell. And I know the 2011/2012 Airs with Toshiba SSD had some seriously high failure rates.

    Must admit, I'm a bit concerned.

    The drives that had the issue were given a software fix or will be replaced under extended warranty.

    Don't worry about it.

    Thanks. Good to know. Nevertheless, can't help but be a little miffed that I paid the same price for a system with 30% less disk performance. Buying a laptop shouldn't have any element of playing the lottery, but I guess it does :p

    Are you sure that those other speeds were not 512GB drives?
    Your speeds from a 256gb seem ok in the ballpark

    Smaller capacity SSDs are slower.

    Question is, do you feel the computer is slow?

    Do you have filevault enabled? That will slow it down.

    File vault not enabled. I'm pretty sure the 700/700 speeds I saw were from a 256gb ssd so size is not the source of the speed difference. I'll double check and post the source of the numbers here.

    Assuming my numbers above are accurate, I do feel that a 30% reduction in disk speed is noticeable. And when I'm paying exactly the same price as the person who gets a samsung drive, not sure why I shouldn't get the same superior performance (and reliability for that matter).

    I have yet to find any other reports of a 2013 MacBook Air coming with a toshiba ssd, so this seems to be a bit of an anomaly.

    Ok, here's a YouTube review showing write of 670 and read of 720: It's a 256GB HD.

    This one shows 600+ write and 675+ read: Not sure of SSD size. But it can't possibly be a 128GB with a write speed that fast.

    This reports speeds of 670/720:

    Various other reviews that used a 128GB SSD (so it had significantly slower write speeds, as compared to a 256GB SSD--as expected) showed read speads of 700+.

    So yeah, a Samsung 256GB should definitely be pulling 600+ write speeds, and read speeds of 650-720.

    My 256GB Toshiba is plunking along at 490-505 write speeds, and 580-610 read speeds. That's about 20% slower than the Samsung.

    And again, beyond the speed (which may not be a significant concern of itself), the Toshiba seems to be very rare in the 2013 MacBook Air (haven't seen a single other report of a Toshiba SSD), and had serious reliability issues in older MacBooks.

    So yeah, my Mid 2013 MacBook air died on my last week. I had it diagnosed by a pc repair guy and he says the SSD has failed. The MacBook would not recognise it as being in the machine. This is also a Toshiba 25gb SSD, so I can't help but feel I have had the same issue as the 2012 models. I have been doing a bit of reading up and you are right, it seems the Toshiba SSD is much more rare in the 2013 models, with most having Samsung SSDs. Really annoyed as the machine is out of warranty and I don't want to have to fork out loads to Apple to fix something that may be inherently faulty!
