It seems as though Hard Drive manufacturers will never rest until they absolutely drive me insane. A few weeks ago, I was able to review a hard drive by a company named Western Digital that sported 250 gigs of space and a speedy interface. Recently, they decided to tease my with a new drive that slams 400 gigs of space in your face and a tad bit slower interface. Rhyming unintentional. Enter the WD4000KD, a SATA drive with a whopping 400 gigs of space and a 16 MB cache at a not so whopping price of $234.99 (WD's website price - Bare Drive); that's only .59 cents per gig.
