You may recall that Apple also ships faster Samsung drives in some MacBook Airs, that appears to still be going on with the 2012 updates which suggests the tested Toshiba flash drive is probably slightly slower than a Samsung model, though the performance difference between the two drives is likely to be completely negligible at this point.Īll read and write speeds were benchmarked with DiskSpeedTest, a free disk testing app available from the Mac App Store.Ĭan anyone tell me whether they have some sort of daemon workaround for the situation when the whole disc gets full and you need to write over a previously written area? You all know (i suppose) the major SSD flaw is that you will be enjoying that speed only until the last byte of that SSD has been written to, after which time major slowdowns will occur. The SSD tested with the MBA 20 models are Samsung. Interestingly, the SSD tested within the MBA 2012 is the TS128E model, a Toshiba drive.

You can attribute that to the ultraquick flash storage. It is difficult to convey just how fast the newest MacBook Air is, but it’s safe to say the performance is extremely impressive and I haven’t ever used a laptop that feels faster. MacBook Air 2010 SSD: writes at 157MB/sec, reads at 188MB/sec MacBook Air 2011 SSD: writes at 152MB/sec, reads at 145MB/sec MacBook Air 2012 SSD: writes at 364MB/sec, reads at 461MB/sec
