I have the 13" 2011 MBA 4,2 with 256GB SSD. Love this machine, but the smaller form of the 11" MBA would work better for me for commuting, etc. I'm thinking about buying a 11" 2012 MBA 5,1 with 64 GB SSD, but I want all the content of my current MBA to make it to the 11" MBA, and for cost I'd rather get the 64 GB 11" and transfer the older, higher-capacity SSD into the newer machine. Is it possible to transplant/swap the SSDs from these 2 machines? The process of switching drives doesn't worry me, I just want to make sure these 2 machines have compatible SSDs. Thanks!
