The boot drive in my 2010 Mac Mini Server Edition has gone belly up and needs to be replaced. Its been a while since I bought it and I cant remember what the exact limits are on combined thickness of the drives in the two available slots. Only one drive is dead, but my initial thought is if Im going to be opening the thing up and mucking about in there, I might as well upgrade both drives. It came with 2x500 gb onboard, which was good back then, but times have moved on quite a bit. However I want one of the new drives to be an SSD., ideally a 1TB SSD such as the Crucial M550 or Crucial BX 100. Question is: assuming an SSD in one slot, whats the biggest physical thickness possible for the second drive? For that slot, Im looking at the WD Mobile Green 2TB. This is a 15mm height and am wondering if the combined height would be doable.
