Long story short: I am in a location where the only rMPB I can economically buy is the 2,3 GHz with a 256 GB SSD. Unfortunately, that is not enough space for me in the long term. However, I saw this Mac parts store advertising Apple SSDs for the rMBP. I emailed them to ask if these SSDs are, in fact, new products. Of course they said "yes." Has anyone had experience with this business? ps - yes, I know it seems ridiculous to spend an extra $700 just to swap out a 256GB for a 512GB, but the only option I have to buy the 512GB outright is in local currency which would give me the 512GB for about $100 more than buying the 512GB from a parts dealer.
