From PC World review.
Maxtor's speedy, user-friendly drives win as Best Buys in both our 7200-rpm and 5400-rpm categories. The 7200-rpm, 60.5GB DiamondMax Plus 60 ($300) was the fastest drive in our tests. Maxtor's 40.9GB DiamondMax VL 40 ($180) beat nearly every drive in the 5200-rpm category (excluding its cousin, the DiamondMax 80) and also outperformed two of the 7200-rpm competitors. Each hard drive comes with a very good upgrade kit and offers ample storage at a moderate cost per gigabyte.
They tested 4 brands including 75GXP 45 gig and 75 gig. All Maxtor drives easily beat other brands in copying large chunk of files. Yeah even 5400rpm Maxtors handily beat 75gxp in that regard. But IBM was faster by slight margin in some applications like Photo Shop, Access, Photo Paint, though.
I personally use Maxtor, and it's fast and quiet. My old IBM is slow and damn loud.
