I avoid Maxtor drives whenever possible, which for me means I never use Maxtor drives. In the past I had several older ones die on me (okay, every Maxtor I have ever owned). These drives were in the range of 1.6 gig through 6.8 gig. No, they didn't just recently die either. They died not too long after I bought them new. For that reason I stayed away from them for a long time. I was thinking about giving them another chance at one point and then a friend of mine that swears by Maxtors had his drives dropping off left and right. These the the normal 7200 RPM 2 meg cache, ball bearing or fluid dynamic bearings, then 8 meg cache drives. I won't blame it all on Maxtor, since my friend sometimes didn't properly ventilate his case. I will say that in my experience, Maxtor drives generally run hot and don't like hot temps.
On the other hand, I have not had a single one of the 6 WD drives die on me in the past 4 or 5 years. They all run great.
