The Addonics Diamond Cipher Drive Cartridge System Kit (DCDCS) features the new generation of eSATA hard drive enclosures with 256-bit AES hard drive encryption to ensure absolute data security should the drive get stolen or lost. The crypto engine inside the Diamond Cipher enclosure handles all encryption and decryption on the fly with no detectable performance degradation on data transfer. Using the native eSATA interface, the Diamond Cipher Drive Cartridge System supports the highest performance possible through an externally connected hard drive enclosure. By attaching different IO converters, the Diamond Cipher can also be interfaced to IDE, USB or SCSI ports.
