I've had more Maxtor drives die on me then any other HDD type... but I've also had a lot more Maxtor drives. I've never had a seagate drive die on me, but I've only owned one or two. I've only seen a few dead WesternDigital drives, and they were all older then me, so I wasn't shocked.
My current analysis of HDD makers:
WesternDigital: Really good, hardy drives... but are they worth the price?
Seagate: I trust these a little more then Maxtor made drives. I find them reliable and speedy.
Maxtor: I buy a lot of these because they are cheap, and I don't really have any complaints about them. They can be fast, and good drives too. The newer models are quite nice! My SATA drive is a maxtor
and is also my favourite HDD right now
IBM: I have one of these... it's 80GB and the slowest thing I have. If it wasn't for the large capacity it would be back sitting on my desk being used as a paper weight, where its' already spent a great deal of time being. I would NEVER buy one of these again! My mother bought one with me at the same time I bought mine, and her's has died and been replaced on warrenty twice! The warrenty is now over, but so far this one has worked for her. I know I'll trade mine out as soon as I get a new HDD, but due to the drive's size, I'll probably still keep it around for non-essential file storage (like TV shows and movies).
