Hitachi works on 5TB Hard Drive

Hitachi hopes to roll out a 5TB hard drive by the time 2010 rolls around, claiming that its CPP-GMR (Current Perpendicular to the Plane Giant Magnetoresistance) technology is able to surpass the 1TB/inch barrier within 2 years’ time, making way for a 5TB 3.5″ hard drive a possibility then. A device that small (relatively) with such a huge capacity will be a boon, and it will definitely be interesting to see how SSD manufacturers fight this battle out. Will space or efficiency rule the day then?
