I am wondering what kind of SSD is stock in the Rev A MBA and how much you could sell a used SSD for and also what are some good options to swap out that out for a 128GB SSD - I know the Runcore is out there - any other options?
Other than the RunCore, PhotoFast is about the only other option.
Recent listings on eBay have new 64GB SSDs for the Rev. A in the mid-$200's, so I would imagine a used one would have a hard time getting more than $200.
Having owned/used all three (stock 64GB SSD, PhotoFast 128GB SSD, and RunCore 128GB SSD) in my Rev. A the clear performance choice is RunCore.
