MacBook Air SSD Benchmarks: 2010 vs 2010

An interesting test comparison between MacBook Airs with and without FileVault turned on has been making the rounds. I was ready to publish a link to this post, but then I decided to run the FileVault ‘on’ test with my MacBook Air. Here’s where my numbers fall in comparison to the linked posts: Machine: 2010 […]

An interesting test comparison between MacBook Airs with and without FileVault turned on has been making the rounds. I was ready to publish a link to this post, but then I decided to run the FileVault ‘on’ test with my MacBook Air. Here’s where my numbers fall in comparison to the linked posts:

So my machine performs better in most tests — what needs to be noted is that the machine specs are vastly different. Jay is using an 11.6″ Air with the 1.6 Core 2 Duo processor, 4GB of RAM and the 128GB Toshiba SSD. I am using a 13″ MacBook Air with a 2.13 Core 2 Duo processor, 4GB of RAM and the 256GB Toshiba SSD. I am not sure if it is the processor, SSD size or the possible difference in free space on the drive accounting for the difference (or all of the above) — but there is a difference. Even with the performance difference I still don’t notice it.
