Hitachi GST has announced the latest additions to its CinemaStar family of 3.5-inch hard drives, the 7K1000.C and 5K1000 CoolSpin. Both of them are available in a range of capacities from 160GB to 1TB, using 500GB per platter technology, and are pitched as the perfect solution for consumer electronics applications such as HD DVRs, DVD/HDD recorders, and media centers.

The latter drive in particular features the company’s CoolSpin Technology, which supposedly relies on motor speed optimization to provide a balance of performance, power utilization and acoustics. According to Hitachi GST, this enables the CinemaStar 5K1000 CoolSpin to consume less than three watts at idle and operate nearly silent at 2.4 bels, although the company is not giving an exact spec on rotational speeds.

The 7K1000.C spins at 7,200 rpm and the 1TB capacity will allow both drives to store up to 250 hours of MPEG-4 video and handle multiple simultaneous streams. The CinemaStar 7K1000.C and 5K1000 will be available in volume starting Q4 2009, but pricing has yet to be revealed.
