According to bit-tech.net, Western Digital is working on a 20,000 RPM Raptor hard drive to combat the ever-increasing pressure from SSD manufacturers. As the experts claim, SSDs are going to be affordable in the next year. HD manufacturers are starting to get concerned about what such SSD’s could do to the market in the near future, especially in the sectors where performance is more important than storage capacity. Western Digital’s Raptor will be very similar to the recently-released VelociRaptor (a 2.5in drive with a custom 3.5in housing system). The drive will be ’silent,’ in spite of the impressive spindle speed (20,000 RPM). The device manages to be so quiet thanks to new improvements in housing technology, which work both as a heatsink and as a noise inhibitor.
