Summary: I tend to try to choose hard drives for features that seem to increase longevity even if I have to sacrifice some performance. I bought two devices. Unfortunately, one of them failed - though glad to say, it failed during warranty. WD did ok by me. They replaced that drive with a 750GB unit. I'm not sure whether to look at the drive failure as an indication of product-line quality problems or not, but I still like the drive.
Summary: I build computers and have tried many drives. The only drive I have found that lasts and is reliable is the Western Digital Brand. I use the smaller 250GB drive as a boot drive and this does the job perfectly.
Summary: If you have a slow CPU, you should buy the fastest HD, one with a 32 MB cache, and 7,200 RPM and SATA 3.0 if your motherboard supports 3.0 GB's Hard Drives
Pros: I got this puppy for 35.00 and free shipping, packaging was excellent, with plenty of cushion, I love buying instant discount items, with free shipping, which was fast, that alone would cost $8 to $10 alone
Cons: None at all, but if you want the best in performance, a 16 MB or 32 MB boult in cache is best, 2MB would be the slowest.
Pros: Good price for a nice amount of storage. Easy to install, quick to format and good read speed. Bought two of them right away for a build and they both were smooth installs from physical installation to visibility and usability in XP.
