Western Digital busts out two-platter 640GB 3.5-inch hard drives

Sure, you've been able to score a four-platter 1TB hard drive for over a year now, but the cooler, quieter, economical and speedy two-platter hard drive has always been a bit of a sweet spot for storage, and Western Digital has finally hit that mark with its new WD Caviar SE16 640GB SATA drive. The 3.5-inch disks hold two 320GB platters, boast 3GB-per-second transfer rates, and are available now for $140.
