I presume you're asking about IDE hard drives?
If so.. Id go with a Maxtor drive 740K-JL ? not sure if that model # is correct but its the model with the liquid bearings. They are fast, quiet, and they operate very cool.
Other than Maxtor.. I have personally used western digitals and seagates. I have never had any luck with WD's, they always seem to die on me. and with seagate drives; they run way to hot.
