Man, this is like the 3rd or 4th thread I've seen in the last couple of weeks regarding this subject.
Anyway, with the exception of IBM "Deathstars", I've never had any issues with any of the top brands. I've gone through numerous (hundreds actually) Maxtors, WDs, and Seagates over the years. This includes not only private use, but at work and also for the machines we supply our numberous clients. Sure, there could be a dud or two, but it's not inherent to any particular brand. It could happen to any of them.
There WAS a span of time when an entire production batch of WD 40gigers seemed to die prematurely, but WD seemed to have worked that out. My current favorites are the 16mb cache Maxtors which seem to be the best combination of speed and noise.
