That's a good find for the general masses. For those who want absolute quiet, the IBM may be a better go, but WD drives are pretty reliable if taken care of. By the by, to toss my $.02 in on quality across the board, I personally have owned 2 WD drives that haven't gone bad, a 1 gig and 13.6 gig. I have 1 5 year old 1 gig IBM that keeps chugging away, high quality stuffs. I have seen 1 quantum fail on me (formerly in a Mac) and seen a catastprohic failure on a 5.25 bigfoot ( stay far away from those). We have a good amount of Westerns at our small office and the only ones that have failed have been shocked to death due to the carpet from hell. From experience at my old job and current, IBM and WD all the way.
As fas as Maxtor ... they are noew responsible for me losing 4+ years of college files, including many papers. I bought a 3.5GB with my first computer ( a K5-166). It died after 2 years.. no reason. Lost a few years worth of work. Got it RMA'd and bought a burner this time. Backed up every thing I could. 1 day the hard drive crapped out while I was trying to finally do a complete backup. This was a whole month after the RMA. Nice drives. I complained this time and got a 8.3 GB drive in return since they no longer made the smaller one. More lost files. Sold the Maxtor to my sister nad bought a WD. My brothers (2 MCSE's) have gone through a combined total of 7 Maxtors through RMA and have finally given up. They both forfeited their last warranty rights cause they don't want to put the pieces of garbage in anyone's computer anymore. Don't trust em. Nothing but trouble.
You want 40 gigs plus ? You should buy either this or a 75GXP 45GB. And toss your current Maxtor out a window if you have one, so that it may not spread its disease anymore.
