There's a preview of the hard drive here.

And for the lazy, here's a quick summary:
"As impressive and respectable as bringing a 10,000 RPM drive to the Serial ATA market is, the Western Digital Raptor, in its current state, does not cut it. The drive exhibits all of the characteristics of a 10,000 RPM SCSI drive, including the high pitched whine (arguably more annoying than either of the SCSI drives in this roundup) and very low access times, but without the overall performance of the 10,000 RPM SCSI drives we're used to."

Looks like the new WD is a dud
