Some MacBook Airs Shipping with Faster SSDs
MacBook Air SSD via iFixit
Anandtech summarizes findings first reported in our forums about SSD brands found in the MacBook Air.
In iFixits teardown, it was confirmed that the MacBook Airs use Toshibas Blade X-gale SSDs. A bit over month ago, however, it was discovered that there appear to be two different revisions of SSDs circulating in MacBook Airs. The first one is obviously the Toshiba, but later user reports show that there is a second, totally different SSD. This SSD carries a model name of SM128C while the Toshiba is TS128C. The SM in the model name hints towards Samsung as the manufacturer, and Apple has used Samsung SSDs before.The significance in the finding is that the performance of the new SSDs is notably faster than the original Toshiba one.
Based on a survey of the forum thread the results seem mixed even for recently purchased notebooks.
