More compact, this new case design adds minimal height to a drive. Store drives on a shelf vertically - this case is steady while standing up. WiebeTech has gone trayless with the TrayFree™ bays in the RTX™ series, you'll 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. The case is made with textured (for better grip), anti-static plastic. A label area (label included), lets you mark it up however you please. 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.
