The RDCSSAES Ruby Drive Cartridge System Kit is designed to enable any 2.5" SATA hard drive to be use like a tape cartridge via the standard 3 1/2" drive bay of any computer. You can swap hard drive in and out of your computer without restarting your system. Instead of a slow tape cartridge, you enjoy the fast performance of the SATA hard drive. With an optional external power adapter, the RDCS can also be installed externally for different types of applications. Once the OS detects the presence of the RDCS enclosure (cartridge), it appears as an additional hard drive to the system. There is no driver to install or special software required to do data backup or restoration. Data is stored uncompressed in its own native file format and can be accessed readily by any application program.
