Ruby II Drive Cartridge System


The Ruby II Drive Cartridge System (RDCS) is designed to enable any 2.5" SATA hard drive to be used like a tape cartridge via the standard 3 1/2" drive bay of any computer. You can swap hard drives 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. For more detail on drive cartridge system, please visit the following tutorial page.

The Ruby cartridge, small enough to fit easily in the palm of your hand, is designed to handle shocks and perform reliably in mobile applications or rough environments with a patented shock proof rugged anodized aluminum housing. The Ruby drive enclosure comes with both an eSATA and SATA connector. The eSATA connector allows the Ruby drive enclosure to be used as an external eSATA hard drive using a standard eSATA cable and an optional power adapter. The SATA connector allows the Ruby drive enclosure to be used as a removable cartridge in the Ruby drive cradle installed inside the 3 1/2" drive bay on any computer. The Ruby drive enclosure can also be attached to the USB port of any computer with an optional USB 3.0 - eSATAp adapter.

Opening the drive enclosure Installing drive into the enclosure

Coming with a built-in Addonics SATA direct bridge interface, the Ruby II drive enclosure allows the SATA hard drive to appear as a direct connection to the host both in eSATA mode or SATA mode while at the same time isolating the SATA hard drive power and data connectors from the wears and tears incurred in some of the removable SATA hard drive system.

The Ruby drive cradle, equipped with both standard 4P and SATA 15 -pin power connectors, has integrated SATA connector for direct connection to the SATA port of any system. By attaching different IO converters, the Ruby drive cradle can also be interfaced to IDE, USB or SCSI port.

The Ruby II drive enclosure support full 6G data transfer to ensure maximum and stable connectivity of the latest 6G SATA III hard drive and SSD.
