Western Digital are really high in performance, but a bit too loud, and they end up getting screwed up after 2-3 years. MAxtor live for a really long time, very quiet, but low performance. Hitachi are very good too, they are built like tanks! I don't know much about the others. There's another one that you listed, Fujistu or something like that. That was my first hard drive, 6.02 GB, I had it for about three years. It ran HORRIBLE!! It was so slow, 55RPM! YEAH!! NOT 5500, 55 RPM!! ALso, the board under it, the chips blow up pretty quickly.
