I had a Maxtor DiamondMax Plus 9 120 gig HD with 8 mb of cache and a 3 year warranty. It was pretty loud at times. I brought it back though after i got my WD 1200 JB with 8 mb of cache and a 3 year warranty for a really low price! For some reason the WD 1200JB 8 mb of cache HD in my opinion is quicker but maybe i haven't used it enough tell yet. So far it seems just as fast as the Maxtor if not maybe faster. Hard to say. I did make sure it was a two 60 gig platter WD 120JB HD though. WD was so smart to start making their Hard drive packages clear so you can see the model number, LBA number, etc right on the drive without even opening it up! Finally a hard drive company trying to please everyone! Now i can always be picky and look at each hard drive in the store LBA, model number, etc before i buy it to make sure its the exact one i want!
