IMO = In My Opinion
These which IDE hard drive threads do I want come up at least once a week.
The results are always the same.
About 5 in 10 say IBM, 4 in 10 say Maxtor, and the otheres (WD, Fujitsu, Seagate, etc) get very few votes.
The Maxtor Diamond Max Plus ## and IBM ##GXP series are both excellent you can't go wrong with either. Since IBM wasn't on your list, Maxtor (if you will consider IBM, just get whichever is cheaper or easier to find, both are great).
Of Maxtor, the DMax+60 is the best one currently, failing that, DMax+45. Personally I use IBM 75GXPs in my Rig, but I have friends that use the Maxtors and they are good drives to, and Maxtor has excellent RMA service should you need it.
