Western Digital's Caviar SE16 is the latest hard drive to jump on the 300MB/s bandwagon, and fortunately, this Caviar is sporting more than just support for a faster Serial ATA interface. The drive also features a beefy 16MB cache and a stealthy all-black aesthetic that's unlike any other hard drive on the market. Curiously, though, Western Digital has elected not to support Native Command Queuing (NCQ) on its latest high-performance desktop drive. Will that decision hurt the new Caviar's chances against the latest NCQ-equipped Serial ATA drives from Hitachi, Maxtor, and Seagate? Let's find out.
