DESC: Lets you quickly add and remove your Ultra 320/160 SCSI hard drives without having to power down your computer. Perfect for using multiple operating systems, making high-speed, high-capacity backups or for mission-critical PCs or servers, this two-piece removable storage unit consists of an outer bay that mounts into a 5.25" bay on your PC, and a removable drive caddy that holds your 68-pin SCSI drives. To protect your important data, the DRW150SCSI features a locking mechanism to prevent the drive from being accidentally removed while in use and a built-in alarm that alerts you if your drive temperature gets too high. An affordable solution for data storage and transportation between PCs, the DRW150SCSI's compact, light-weight aluminum construction makes the drive drawer easy to transport while helping to dissipate heat away from the drive. The dual ball-bearing fans keep air flowing through the case, helping to keep your drive temperatures at optimum levels.
