PowerEncrypt

PowerEncrypt hardware encryption is now included with the SATA III version of the Overland Tandberg RDX QuikStor drives***. RDX PowerEncrypt data encryption can be added to all RDX media encrypting data written to RDX media with AES-256 XTS standards. Data access is restricted to only those having a password key deployed with the RDX Manager software.

In addition, software encryption is supported for all RDX drives, including external RDX QuikStor drives and RDX QuikStation removable disk appliances.

Fixed Disk Mode for Windows Backup

RDX QuikStor provides a fixed disk mode and allows a seamless integration into windows-backup.** Windows-Backup of current operating systems does not support removable media any more. Users are constrained either to refrain from an operating system upgrade, or to use a third party backup software.
