I've always loved quantum drives, if you can find any atlas drives floating out there or want the Maxtor offering. You will need an adaptor to convert it to 50 pins.
I have Seagate baracuda and hawk, quantum lps, maverick, viking and atlas, old maxtor ones (slow), fuji (nasty:(), and digital (out of some really old servers...) All of which work fine in my 3000's...
Have fun!
