I built my desktop about 4 or so years ago, don't put all that many hours on it, used WD drives. Recently had to unplug one before it quit altogether and one of the other 2 is getting pretty noisy. Started researching for a good dependable drive, with new models coming out so frequently what was a good drive last year may not be true any more. I had looked at Seagate Barracuda LP 5900 rpm drives, but have read some user reviews that say they haven't lasted long for some users. Haven't read any reviews of the WD LP 5400 drives yet. Seek time isn't as important as drive dependability - don't want to have to buy 2 drives just to ensure I don't lose data. I know drives can fail, but being you folks probly have a good read on what's considered the most reliable new drives in the 1 to 1.5 TB size, I'm asking. Thanks!! EDIT: Kept reading reviews, WD Green or Blue or Black didn't exist yet last time i got into this in depth. Read a bunch of reviews, decided on the Black because of the warranty & reviews. Wanted a 1.5TB but they don't make a Caviar Black in that size. But a good price at $99, I'll probly add another one sometime later.
