Hitachi to cram 4TB on desktop hard drives by 2009
By
Hitachi Global Storage Technologies plans to announce Monday it has developed technology that will quadruple the storage capacity of desktop hard drives within the next two years. The new reading-head technology will allow the company to cram more data on hard drives, enabling desktop and laptop drives to store 4TB and 1TB of data, respectively.
The CPP-GMR heads will enable the density of disk storage surfaces to increase to 500Gb per square inch or more in the near future, Best said. The greater the density of the storage surface, the more data the surface can hold. The current density stands at about 200Gb per square inch, he said. The technology will help to meet future storage needs fueled by video and Web 2.0 applications, Best said.
