That's the world's largest capacity 1.8-inch hard disk drive right there. A claim met by a list of specs going a little something like this: 3.0Gbps SATA interface, 320GB capacity, 5,400 RPM, 16MB buffer, and 19dB of emitted noise during seeks -- a 4dB cut from Toshiba's previous generation of 5,400 RPM 1.8-inchers. Of course, these 1.8-inch mechanical HDDs are the form factor most commonly found in those netbook-shoving CULV thin-and-light ultraportables now coming onto the market. Look for it in December when the MK3233GSG hits mass production.
