Hello all, I have a quick question, I have an internal hard drive taken from an iMac, and I wanted to turn it into an external drive. I know there are various kits available to to do this, however, I was under the impression that hard drives come in only a few standard sizes, 2.5" and 3.5" for example. When I measure this drive, it seems to be almost 4" (Width) 5.5" (Height) and 1" (Depth) Can some one please explain to me, which type of enclosure I should get? And also, which would be the fastest type of transfer possible, firewire or thunderbolt etc? Thanks in advance.
