Summary: The hitachi hdd I had in my Lenovo T500 was to small so I replaced it. I took this model over the wd blue just because of the guarantee. I was sceptical about the noise (the hitachi is a very quiet hdd) but the difference isnt very big.
Pros: 5 year guarantee, slightly faster than my old Hitachi 5400 rpm drive but not very faster in everyday use, not noisy how I expected it to be and how people say it is, no vibrations at all.
Cons: In idle a low noise is present which is not constant but oscillates from time to time. In use there isn't much difference, noise is there but the oscillating dissapears.
Summary: This is my second WD Scorpio Black drive to fail within the warranty period. WD is pretty good about their RMAs, but it'd be better if it would just last a few years without flaking out. One more year and I would have replaced the entire computer anyway...
Pros: 5 year warranty, high performance (at the time of purchase)
Summary: Another reviewer's uploaded images show a well packed drive in a factory-style shipping carton. That's not what I got. The drive itself is a Western Digital Black, sold worldwide. These drives are reliable, and essentially silent.
Summary: I don't know if I received a defective batch or what, but every single drive I purchased eventually failed, most recently yesterday. The others failed after 7 months and 14 months. They were RMA'd and so far none of those have failed.
Pros: high performance, inexpensive, 5 year warranty
Summary: A Tale Of Two Hard Drives. Bought 1st drive here in April of 2011. Brand new drive was bad. Newegg RMA'd it for me without a problem. That drive just developed a couple of bad sectors a few days ago. Beyond Newegg's 30 day replacement time so I RMA'd it with WD.
Pros: 500 GB, 7200 RPM in a laptop hard drive. Newegg satisfaction policy! Western Digital 5 Year Warranty!
Summary: Bought to replace the tiny 60gb drive that came with my PS3. With the number of digital games these days 500gb is a pretty good choice. Installation was easy and this drive works like a champ. I think it's great for the purpose.
