What is the simplest / cheapest external caddy to get for my mac pro? i need to use it to frequently back up my 2 x 1tb hds onto 2 other hds, so it needs to allow hds to be easily removable and support 1tb data hds. I had an ebuyer value one for like 4 pounds 98p (what happened to my pound sign?! ######) and it did USB 2.0 and firewire and sata. I got it a year ago. But they dont sell them any more and the cheapest one on ebuyer now is something like 24 pounds, which seems rather excessive. Googling is turning up nothing. Does anyone know what happened to the cheapo ones? Or where I can get one for a reasonable price? thanks!
