The RTX Secure 410-3QR hard drive enclosure brings ease of use, flexibility, and encryption to RAID portable storage. Strong AES 256-bit encryption protects your data if the hard drive falls into the wrong hands. CRU encryption is hardware based and encrypts every sector of the drive including boot sectors, swap space, and temp files. Data is encrypted in real time in the hardware completely independent of the operating system. A physical key is used to encrypt, decrypt, and grant access to the data. This means your important and sensitive data is safe. TrayFree bays make adding drives effortless. It's as easy as opening the door, sliding the drive in, and closing the door. No screws, no trays. It just works. The state-of-the-art hardware RAID controller built into RTX Secure 410-3QR offers RAID 0, 1, 10, 3 and the highly sought-after RAID 5.
