What MODEL SSD can be used?
I love the thoroughness of the EMC 2639 SSD replacement guide...all except for the last photos. They show the SSD being removed...upside down. It's clear it's a Samsung, but there's no listing that I could find of what model SSD is used, and there's no photo of the other side of the SSD. I really don't want to try to buy something off eBay only to find it's just slightly incompatible. Does this need an exact replacement? What drives are compatible?
