Just when solid-state drives were about to catch up to the spinners, Hitachi has gone and announced that it is working on a 5TB hard drive. It says the drive should be available by 2010 in a 3.5-inch format and will use perpendicular CPP-GMR tech to achieve some serious density. Just to show off, Hitachi's Yoshiro Shiroishi pointed out that the human brain has been estimated at (only?) around 10TB. So there we have it -- we're halfway to intellectual obsolescence. Don't say we didn't warn you!
