I find Fujitsu drives (desktop or laptop) to be intolerably poor performers speedwise. IBM rules the laptop market, and their desktop drives are welcome in any of my machines anytime.

Quantum desktop drives are awesome performers, cool and reliable compared to the other extreme: Western Digicrap.

Maxtor have almost always been good solid performers, and Seagate lost my business forever due to flaws on two generations of their drives.
