Western Digital has increased the size of its single platter for dual-platter drives to 320GB, giving these drives a total of 640GB. “That’s not a large capacity drive!” you say. And you’re right, but dual-platter drives aren’t about capacity, they’re about performance and price.
Spinning at 7200RPM, the drives are fast, up to 3Gb/s sustained transfer. These aren’t for large-library media buffs. These are for hardcore video editors, encoders, and server applications. And damn if they aren’t sexy.
