Western Digital's Raptor WD1500ADFD hard drive ReviewPosted on 2006-06-12 14:26:06 by LSDsmurf
For those with no desire to spend countless hours staring at the Raptor X's drive head dart back and forth across the platter, Western Digital makes the Raptor WD1500ADFD. This drive lacks a window, but otherwise, it's mechanically identical to the Raptor X—same spindle, cache, platters, and theoretically, performance. The WD1500ADFD also sells for roughly $50 less than the Raptor X, making it even more tempting for enthusiasts looking for a speedy storage upgrade.
