We're sorry to break the bad news, but that 5TB hard drive you bought last week? Yeah, it's already obsolete. Seagate has started shipping the first-ever 8TB desktop hard disk, doubling the 4TB capacities that seemed huge just a couple of years ago. If it's any consolation, though, this machinery isn't ready to go inside your hot gaming PC. Right now, all those terabytes are destined for data centers where capacity trumps every other concern; Seagate isn't mentioning prices, but enterprise-class storage is rarely cheap. You may want to set aside some money all the same. These extra-roomy drives have a tendency to filter down to the mainstream pretty quickly, so you may soon have more free disk space than you know what to do with... at least, for a little while.
