Ratoc USB 2.0 to Ultra SCSI Converter

Ratoc USB 2.0 to Ultra SCSI Converter More Like This The USB 2.0 to Ultra SCSI Converter opens the world of high performance SCSI devices for systems featuring USB 2.0, but no SCSI ports. Attaching the converter to an Ultra SCSI storage device allows it to behave just like a USB 2.0 device. Unlike many competing converters, the converter is Ultra SCSI rather than SCSI II based, so it offers high performance of up to 20 MBps. The converter interfaces with a wide range of SCSI based drives, scanners, CD-ROM, CD-R/W, Zip and other devices. The unit can be used by itself when used in conjunction with SCSI devices that provide power on the SCSI Termination Power output pin. Otherwise, purchase the optional power adapter in addition to the unit. The device's small size and light weight, makes it an excellent choice for mobile uses. For external SCSI devices only.
