An interesting little titbit around Apple change supplier from Toshiba to Samsung for their Macbook Air SSD storage, which seems to have delivered a nice little performance boost. Could this be a foreboding of a Core i5 update to the Air in June?
Anandtech has run some speed tests on the two blade SSDs and found that the original Toshiba device with the model number TS128C has a read speed of 209.8 MB/second and a write speed of 175.6 MB/second. That’s slower than the newer Samsung SSD with the model number of SM128C. The Samsung SSD has read speeds of 261.1 MB/second and a write speed of 209.6 MB/second.
While that read/write speed increase isn’t astonishingly faster, it is noticeable in real-world use. It’s also important to note that Anandtech can’t confirm that the newer SSD is manufactured by Samsung, but it is likely that is who makes it since Apple has used Samsung SSDs before and because the performance of the SSD matches Samsung’s 470 Series of blade SSDs.
