Does this whitelist drives that report themselves as a manufacturer of "Samsung", or does this whitelist drives that report themselves as "Apple".

If it's the latter, then they've functionally prevented me from ever upgrading a computer that I've purchased from them to add a new, larger hard drive. Now I cannot purchase a Samsung SSD from a third-party and have TRIM support (despite the fact that they ship the same drive, only changing the name reported as the manufacturer). Worse, a cursory glance at the store suggests that they don't sell SSDs as accessories, so I can't upgrade my drive at all and get TRIM support, even at crazy high Apple markup.

(I didn't find this advertised, but I suppose it's possible that the Apple Store may do this upgrade themselves, it seems totally crazy that Apple would completely prevent me from upgrading my disk.)
