Hitachi announced that it has started shipping its first 3.5-inch hard drives that will feature 1TB platters. The newly announced HDDs will be a part of Hitachi's Deskstar and Cinemastar 7K1000.D and 5K1000.B series.
Both drives will be available in capacities ranging from 250GB to 1TB and will feature 32MB of cahce and SATA 6Gbps interface. The difference between the 7K1000.D and the 5K1000.B is in the spin speed, 7200 RPM opposed to 5400RPM.
When compared to previous models, the new 7K1000.D offers up to 15 percent less power consumption in idle mode while the 5K1000.B saves up to 23 percent of power in idle, when compared to the faster 7K1000.D. Both can be attributed to Hitachi's Coolspin technology.
The Cinemastar version of the same drives is pretty much identical except for the A/V streaming optimization. The Desktstar models are already shipping while the Cinemastar version should be available in next few months.
