General Description
The StarTech.com U3W 160Mbps SCSI drive drawer is an aluminum drive caddy and
receiving bay for internally mounting 3.5" 68 pin SCSI drives into half-height, 5.25"
peripheral bays. This allows SCSI hard drives to be quickly added or removed from any
PC with an available 5.25 inch drive bay without opening the computer. The 2-piece unit
consists of a bay that mounts into the PC, and a removable drawer or caddy that encases
the hard disk. A locking mechanism controls power to the drive to prevent it from being
removed while operating. A handle activated drawer release mechanism allows the drive
to be inserted or removed with minimal force. Dual front mounted ball-bearing cooling
fans provide fresh cool air-flow over the hard drive, preventing overheating and data
loss. The Removable Hard Disk Drawer is perfect for educational use, where the same
PC needs to run several different operating systems, high speed, high capacity backups,
hot-swap server drives, or any mission critical PC where downtime must be minimized.
