    Fantastic... It's not as if they have hundreds of hardware configs to test

    Re-install osx! WHAT!

    So if I understand right, these have nearly (or over depending on the old controller) double the read/write speed of the old ones? Reply

    You could argue you need two different NAND supplier, but couldn't they both uses the same Controller? It would have been much matter rather then Lottery picked. The Toshiba SSD was suppose to have 0.1W standby power, if it is indeed a Sandforce Controller that what makes it so much more efficient? Reply

    Apple isn't buying parts and building their own SSD's. They are buying completed drives from the manufacturer so they are going to end up with 2 different drives by default. The reality is that the vast majority of their users won't know or care which manufacturer they end up with for their ssd drive. I'd bet that even those users who do care would have a hard time telling which drive they had just from actually using the machine with out running a benchmark or checking the model number in the hardware profiler.

    I believe your link to the iFixit teardown is bad. The current link to the teardown appears to be:

    Just confirming i received my 11inch 2012 MBA which was a build-to-order 8GB/256GB system and it has the samsung SSD installed. System profiler calls it: APPLE SSD SM256E

    Glad i got a samsung, though it appears the toshiba drives aren't half bad this round.

    Yep me too, I also got the Samsung 256GB "SM256E" in my Air. Mine has 4GB ram. Reply

    There are threads on and the Apple support website for a known anomaly in the behavior of the Toshiba SSD.

    Apparently, Apple is using the Toshiba 128GB SSD and Samsung 256GB SSD.

    When the Toshiba SSD is initially benchmarked on a fresh system, it achieves 360MB/sec writing. But shortly thereafter, something happens with the write speed and it drops to 240MB/sec.

    Once its down to its lower value, it will never go back up. Clean installs, reformat, nothing will ever bring back the 360MB/sec benchmark.

    This behavior is not experienced with the Samsung SSD. It achieves 425MB/sec write speed consistently.

    What could possibly explain this unusual behavior in the Toshiba SSD? Is there a firmware defect in this drive?

    240 vs. 425 is a huge difference. The Samsung SSD is much faster.

    Threads mentioned include:

    Looking to upgrade my 2012 MacBook Air 128GB to a 256GB or 512GB. Do you have any part numbers for the Toshiba or Samsung (preferred) to search by?

    Thanks in advance.
