Techgage.com posted a review of the Western Digital Caviar Black 1TB hard drive. Here's a bit:

Western Digital's 1TB Caviar Black is no slouch of a performer on any front. After the dust settled, it clearly demonstrated the ability to run with some stiff competition on its own terms. If you consider that basically all the other drives tested were either newer or radically different in technology and design, you really begin to appreciate just how well it did perform. Aging gracefully and with class, there is still a large segment of the market in buying these drives for a variety of applications.

The main "pro" for this drive that was almost glaring, was the noise level. All the other drives were far louder and believe me, that makes a big difference to today's consumer. When taking measurements for noise levels, I basically removed all background noise from the testing station and the surrounding area. I can hear a pin drop from 15 ft away with this room configuration. While this may seem an bit extreme, it does showcase what's possibly the most important consideration a buyer will have, aside from density and performance. Quiet is not only expected, it is demanded.

Western Digital is also the only company to still currently offer a 5 year limited warranty. Here again is another area where the competition has slipped over the years. It's also an area where Seagate has given the edge with the lowering of their warranty to 3 years. To the gaming/performance enthusiast, this is almost a non-issue, since they are the one segment that will almost never keep a drive more than a year or two. However, the fast rising group of mainstream/HTPC users will almost undoubtedly be looking for a more long-term solution. With data being measured mainly in gigabytes, it is very important to this segment that their data be safe. While even the best warranty cannot return lost data due to a failure, it is still nice to know you are protected for so long.
