We've improved the design of the DriveBox Anti-Static Drive Case for 3.5" drives. More compact, this new case design adds minimal height to a drive. The case is made with textured (for better grip), anti-static plastic. You need somewhere to keep your hard disks when not in the unit. We know that customers are swapping out entire RAID sets, and are transporting single drives between two locations. Quantity discounts are available, and even custom printing isn't out of the question. Order with hard drives, and they'll ship in the case, already tested and formatted to your OS preference.
