I used to like Western Digital drives, but in the last 6 months I've had 4 of them die on me (1 WD200 20GB, 1 WD204 20 GB, 2 WD400 40 GB drives). I'm now trying Seagate drives to see if they are any better. I had bad luck with Maxtor a couple years ago, so I don't like to use them either.
The special edition Western Digitals look fast, but considering 4 of the 9 WD drives I've used recently have died (one of the 20 GB drives was just last week) I won't touch them again.
