Apple Still Using SSDs With Varying Speeds On New MacBook Air

A couple of month ago, Apple appeared to be using two different suppliers, Samsung and Toshiba, for the solid-state drives (SSDs) on its MacBook Air models. Especially, the Samsung SSDs registered considerably faster read and write speeds than the Toshiba SSDs. User reports specified that Apple was in fact using both suppliers simultaneously, rather making it luck of the draw as to which SSD a user received in a given machine.

Reports are indicating that Apple is continuing to employ this dual-supplier strategy for SSDs in the new MacBook Air, with the Samsung SSDs continuing to provide substantially better performance than the Toshiba drives.

It has been established that a fairly significant discrepancy exists when benchmarking both MacBook Air models over the weekend. The 128GB Samsung SSD in his 11-inch Air is capable of achieving 246 MB/s write and 264 MB/s read speeds. However, when switched to the 13-inch model speeds drop to 156 MB/s and 208 MB/s, respectively, using that notebook’s 128GB Toshiba SSD.
