Western Digital WD1500ADFD: King Raptor

With a $300 price tag, 150GB capacity, and enterprise market heritage, this drive is targeted to a different market. While Western Digital desperately wants the drive to succeed in the server arena, they are acutely aware of the fact that the computer enthusiast will likely be one of the main purchasers of this drive. The Raptor X looks like the drive to have for the serious case modder, but we feel the additional $50 in cost is better applied toward buying a large storage drive for your system.
