Western Digital Launches 4 TB Nearline HDDs

The WD RE SAS and WD RE SATA nearline drive series are also available in capacities of 1 TB, 2 TB and 3 TB for SAS as well as 2 TB and 3 TB for SATA. The 4 TB drive integrates five 800 MB platters.

According to the manufacturer, the 7,200 RPM drives promise a reliability of 1.4 million hours MTBF for the SAS versions and 1.2 million hours MTBF for the SATA models. WD said that the drives also include the company's NoTouch ramp load technology, which reduces wear of the recording heads as the heads do not touch the disk media.

Pricing starts at $139 for the 1 TB SAS model, and goes as far as $479 for the 4 TB version. The SATA models are $20 cheaper than their SAS counterparts.

    The hard drive manufacturers are sandbagging innovation, by milking their old technology.
    They have the capability to produce 5 x 1TB platter drives. 3 x 1TB platter drives have already been available for awhile.

    About time, I really want to see some competition in the larger (4Tb) drive space. Although with all the consolidation in the manufacturers I suppose it is unlikely in the near term.

    7.2KRPM 4TB drive... Those are probably pretty darned fast for an HDD.

    Also, typo in the article. The 4TB drive is not using five 800MB platters. That's be 4GB, not 4TB, so it's using five 800GB platters if it has five platters and has a total capacity of 4TB.
