StarTech.com's IDE66BASIC 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: a bay that mounts into the PC, and a removable drawer that encases the hard drive. It also supports Ultra ATA/66, ATA/100 and ATA/133 IDE transfer rates of up to 133 MB/s. The IDE66BASIC guarantees compatibility with your computer system and its high-quality 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; a ball-bearing cooling fan that provides air-flow over the hard drive, preventing overheating and data loss; dual LEDs indicating drive power and activity status.
