Here's my take on hard drives. They are all made so fast these days that one brand doesn't really seem to be better than another in the long run. Hard drives die all the time regardless of the brand. Hitachi SCSI drives used to burn up all the time, Maxtor and IBM drives are kind of loud, the Seagates have 5 year warranties. The only semi-safe way to protect your data is to run your drives in RAID5 and BACKUP the important stuff on tape, CD, DVD, etc. In my server I run 6 IDE drives (2x160GB, 4x120GB; total usable space=600GB) in a RAID5 array and have 2x40GB drives in RAID1. Some of the drives are WD, some Maxtor, some Seagate. I have lost 2 WDs (one died, one actually caught on fire), unfortunately at the time so my RAID5 was killed. I replaced them with Seagates because they were on sale. I just buy whatever size I need that's on sale. Eventually they will all fail (hopefully not at the same time). However, I also have some old WD drives (1.6 GB) that were supposedly flawed when they were made (the 3 platter version), but they are still running strong.
By the way, the drive that caught on fire was a WD. It was out of warranty, but WD replaced it for free anyway. I think they were a bit surprised when I told them that I had a 4 inch white flame shooting from it. Good thing I had to the case open when it happened! That is a whole story in itself!
