Hitachi Also in 3TB Desktop HDD

The new Deskstar 7K3000 can now be found on Hitachi GST‘s web site.

That’s pretty rare to see an HDD manufacturer not publishing a press release for a new drive, and, more than that, here the highest capacity unit never reached before by Hitachi GST.

Maybe the reason is that the Japanese company is not ready for a public announcement or wants to avoid this kind of comment from the press: HGST is following Seagate that was the first with this record 3GB capacity, and then WD. The firm is not anymore the technology leader in this drive’s category. It was the first one at 500GB in 2005 and at 1TB in 2007.

But both Seagate and WD first announced external 3TB version because most of the operating systems do not accept to manage more than 2.2TB on disks without special drivers. Then WD launches an internal version on 19 October 2010 with 4 platters or 750GB per platter (Seagate uses 5 disks).

The new model is a 3.5-inch drive also available in 1.5TB and 2TB capacities with platters rotating at 7,200rpm but the number of disks and heads is not revealed. Maximum areal density is 411Gb per square inch. It’s the first hard drive from the company with 6Gb SATA interface.

All capacities will ship with 64MB cache buffer. The units show an improvement of up to 27% over previous generation products in PCMark Vantage testing scores, according to HGST. In addition, the 2TB 7K3000 offers idle power savings of up to 30% over former products.

The Deskstar 3000 follows the Deskstar 7K2000 at 2TB and 7,200rpm with 3Gb SATA.

Hitachi GST also offers for the first time an additional HDD, the Deskstar 5K3000, with 1TB, 2TB to 3TB, a 32MB buffer, and the same new interface, but at 5,200rpm only.
