Hitachi was the first to roll out a 7,200RPM, 3.5-inch 2TB hard drive, and it looks like it's now done it again at the 3TB level. That comes in the form of the company's new Deskstar 7K3000 model, which appears to not only be the first 7,200RPM 3TB drive hard around, but Hitachi's first drive with a 6Gbps SATA interface. Otherwise, the five-platter drive packs a 64MB cache buffer, an idle power draw of 6.8W, and what Hitachi describes as an eco-friendly, halogen-free design. Still no word on pricing or a release date, but The Inquirer surmises it'll cost somewhere in the neighborhood of £200, or $320.
