While SSDs continue to come down in price and up in performance, hard disk drives keep ballooning in size. And just when we thought we were becoming spoiled with storage space, Hitachi hits us with a humdinger by announcing plans to release a 5TB hard drive by 2010. That's FIVE freaking terabytes in a single 3.5" drive, or half the storage capacity of the human brain, claims Dr. Yoshihiro Shiroishi from Hitachi. In more concrete terms, 5TB equates to about 5,000 hours of video, or more than a million songs. Throw two drives together and you could store a human brain's worth of porn!
Hitachi's pledge trumps an earlier prediction the company made back in October 2007 when it said 4TB of storage would be likely by 2011. Instead, Hitachi will employ Current-Perpendicular-to-Plant Giant Magnetoresistance (CPP-GMR) magnetic read heads to pack an additional terabyte than initially anticipated, and a year sooner than predicted. CPP-GMR will make it possible to achieve data densities of 1TB or more per square inch, paving the way for even larger hard drives.
Home theater buffs will undoubtedly herald Hitachi's announcement, but what about everyone else? Are we reaching the point of diminishing returns in terms of hard drive space? Post your thoughts in the comments section.
You can take one of two approaches with the gear in your home-theater system: Put everything on display, or you hide your components in a cabinet or closet. If you prefer discretion over exhibitionism, Niles Audio’s Remote Control Anywhere kit lets you to control all your infrared-controlled components no matter where you’ve stashed them.
