They are the same Blade-style SSDs as the previous generation. The chipset uses a SATA III (6Gbit/sec) controller but the SSD connects at a SATA II (3Gbit/sec) link speed...it is a SATA II Blade SSD, but the MacBook Air apparently supports SATA III, which is significantly faster. I would not be surprised if we see some 3rd party SATA III SSD upgrade solutions in the future for the 2011 MacBook Air.
