Western Digital has joined the ranks of hard drive makers offering 1TB of storage capacity in a standard notebook model. The first 2.5" drives to pack a full terabyte did so with three platters and a 12.5-mm drive thickness that's incompatible with most notebook drive bays. This latest Scorpio Blue uses two 500GB platters and slips into a 9.5-mm casing, so it should work in just about any laptop.
With a 5,400-RPM spindle speed, the new Scorpio is targeted at mainstream notebooks rather than high-performance portables. There's only 8MB of cache on board, and the SATA interface tops at at 3Gbps—not that the drive can transfer data any faster. Three years of warranty coverage is standard for mainstream hard drives, and WD doesn't disappoint on that front.
As one might expect, there's a bit of a premium attached. WD says the Scorpio Blue 1TB will sell for $139, which is $50 more than the 750GB Blue. If you want something a little faster, the 7,200-RPM Scorpio Black line serves up 500GB and 750GB models for $70 and $110, respectively. Looks like we'll have to wait a little longer for a terabyte Scorpio Black.
