1.5 petabyte system built with PC hardware


Crave storage capacity? Slashdot pointed me to an interesting article on a low-cost storage racks from PetaBox. The racks use PC hardware, including VIA EPIA-M10000 Mini ITX motherboards and Hitachi hard drives. Despite the Deathstar's checkered past, PetaBox was apparently impressed with the reliability of Hitachi's current drives.
Saikley says Capricorn did extensive testing to qualify hard drives for capacity, reliability, and cost, finally choosing Hitachi. "Although Hitachi does not offer an 'enterprise' or '24x7' SATA drive, our testing found their drives to be as reliable as anything out there, enterprise distinction or not," Saikley said.
Interestingly, PetaBox systems use Just a Bunch of Disks (JBOD) arrays rather than RAID 5, apparently because RAID 5 "does not scale well to petabyte-level storage." A petabyte isn't just a theoretical limit, either. PetaBox recently delivered a 1.5 petabyte system made up of 2,500 hard drives for the Internet Archive.
