Looks like Apple feels the need for speed, and so they have given a speed boost to the solid-state drives in newer MacBook Air models. Most batches were using Toshiba’s X-Gale SSD, but now a more recent model has been spotted using a Samsung-made 470 series drive.

The 128GB drive is of course much faster in reads and writes, taking things from about 210MB per second and 176MB per second in the old Toshiba SSD to 261MB per second and 210MB per second in the Samsung version. The upgraded drive, which Apple identifies as SM128C, also supports Native Command Queuing to optimize how it reads and writes to the drive. The X-Gale lacks that feature. Good news for those looking in a MacBook Air.
