Those 750GB and 1TB mobile hard drives are all well and good, but being thicker than normal, they’re not guaranteed to fit inside your laptop. Good thing, then, that Western Digital has started volume shipments of what it claims to be the world’s highest-capacity 2.5″ hard drive with a standard 9.5-mm thickness.
Shipping now through “select distributors and resellers,” WD’s latest Scorpio Blue mobile hard drive uses two 320GB platters to achieve a 640GB capacity. Those platters revolve at 5,400 RPM, and they sit alongside an 8MB cache and a 300MB/s Serial ATA interface. WD covers the drive with a three-year warranty, as well.
The company says it aims this product at “mainstream notebook computers,” and it seems to be pricing it accordingly, with a $149 MSRP. Of course, you can already get the 12.5-mm-thick 750GB Scorpio Blue for that much at Newegg right now. Both drives have similar specs, but the 750GB model has a slightly slower 5,200-RPM spindle speed.
