WD releases a 640 GB HD

Okay apparently is was already available for two weeks now, but hey .. 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.

The new high-capacity drives are based on the 320GB-per-platter technology the company introduced in January. The new platform was designed for cool and quieter computing. Western Digital is rolling out the new technology across its product lines, including desktop, enterprise, and external hard drives.

The drives are targeted toward users of data-intensive applications, thanks to "performance with their extreme areal density, 3GB-per-second transfer rate, and Native Command Queuing (NCQ)," according to the company.
