You can't really argue with a 5 year warranty, but out of approximately equal numbers of harddisks I've had they were (in terms of failures) a couple of hundred Fujitsus, about 30 seagates, 2 Maxtors and none of the old 4.5Gb Samsungs.
At home at the mo I have Maxtor 20 and 40 Gb harddisks, a 30Gb Hitachi, and a 4.5 Gb IBM in the A3000, all of those work fine. The 1.0 Gb Maxtor I bought in early '96 is still alive and kicking in my sister's PC, too (she uses it for Fortran under Linux).
Everyone has their own favourites I guess ...
