Hitachi Global Storage Technologies (http://www.hitachigst.com/) has announced the industry’s highest capacity 4TB storage solutions -- the Deskstar 5K4000 Internal Hard Drive Kit and the Touro Desk External Hard Drive.

The 4TB Deskstar 5K4000 is a 3.5-inch hard drive with a 32MB cache buffer that provides 33% more capacity compared to current 3TB drives. Its CoolSpin technology, along with other Hitachi power management techniques, purportedly gives the Deskstar 5K4000 up to a 28% idle power savings over Deskstar 7K3000 7,200 RPM drives and an idle acoustic level of only 2.5 bels. The new 4TB Hitachi Deskstar 5K4000 Hard Drive Retail Kit is currently shipping in limited quantities to online and retail stores with a suggested retail price of US$399.99.

The 4TB Hitachi Deskstar 5K4000 Hard Drive Retail Kit comes complete with mounting screws, step-by-step instructions, and a software download that allows 32- and 64-bit Mac OS X, Windows and Linux systems to tap into the full capacity and power of the 4TB drive, as one big massive data drive, without having to install extra hardware. Hitachi GST will be shipping its Deskstar 5K4000 (bare drives and bulk pack) to OEMs, distributors and channel partners worldwide in the first quarter of 2012.

The Touro Desk External Drive can be placed vertically or horizontally. It sports a smooth black, textured body. The Hitachi Touro Desk External Drive now comes in 4TB, 3TB, 2TB and 1TB capacities. The 4TB Hitachi Touro Desk External Drive will be available in January for $419.99.
