PCShopTalk posted a review on the Western Digital RE3 1TB Hard Drives

To test the hard drives, we did a complete reinstall of Windows Vista and completely formatted all hard drives that were tested. We let the computer run for several minutes so the hard drives would heat up and be in standard test conditions. We then ran several tests with these programs listed: HD Tach 3.0.4.0, PCMark 05 and PCMark Vantage. The tests were run 3 times and the results were averaged to get accurate information.
