The Western Digital drive is part of the Caviar SE16 series, which we found to have excellent performance and impressively low noise levels. At 25 cents per gigabyte, that particular 500GB model is a very interesting deal. However, Western Digital only covers the drive with a three-year warranty. For users who'd rather have five-year coverage but still don't want to break the bank, we've noticed that Seagate's 500GB Barracuda 7200.10 can now be had for just below $140. That adds up to 28 cents per gigabyte, which is still very cheap. The Seagate's noise levels aren't as low as the Caviar SE16's, though.
As a reminder, Shuttle still has a five-question giveaway survey going where TR readers get a chance to win one of the firm's SDXi BYO limited edition barebones systems. The giveaway sign-up runs until April 23.
