How much faster is the flash storage on the MacBook Air than SSD? I heard that the flash storage in the MacBook Air is faster than SSD since it doesn't need to go through a SATA interface. How much faster is the MacBook Air's hard-drive compared to a traditional SSD?
It's still a SATA interface, just miniaturized, hence it's name mSATA.
There is a great picture at the following link that shows just how tiny an mSATA drive is compared to a regular 2.5" laptop hard drive.
