StarTech.com's premium IDE66PRODRWR aluminum removable hard drive drawer offers a cost-effective way to quickly insert or remove IDE hard drives from any PC with an available 5.25 inch drive bay without opening the computer. It is an ideal solution for high-speed back-ups of critical files, moving large files from one computer to another, and for running multiple operating systems on the same PC. The unit consists of two pieces: an aluminum bay that mounts into the PC, and a heavy-duty removable drawer that encases the hard drive. It also supports Ultra ATA/66 ATA/100 and ATA/133 IDE transfer rates. The IDE66PRODRWR guarantees compatibility with your computer system and its high-quality aluminum construction offers protection for critical data - meaning you'll never have to worry for the drive's safety as you move it from one place to another. Additional features include: a key-lock mechanism that prevents the drive from being removed while operating; a handle-activated drawer release mechanism that allows the drive to be inserted or removed with minimal force; dual ball-bearing cooling fans that provide air-flow over the hard drive, preventing overheating and data loss; four LEDs indicating drive power and activity status.
