Need additional data security on your drives? Dot Hill offers self encrypting drive (SED) capability that protects your data when removed from their original array. Available in 1.2TB small form factor (2.5”) or 4 TB large form factor (3.5”), these SED drives provide instant data destruction via cryptographic erase. In normal use, you do not need to maintain authentication keys (otherwise known as credentials or passwords) in order to access the drive’s data. The SED will encrypt data being written to the drive and decrypt data being read from it, all without requiring an authentication key from the owner.

When it’s time to retire or repurpose the drive, the owner sends a command to the drive to perform a cryptographic erase. Cryptographic erase simply replaces the encryption key inside the encrypted drive, making it impossible to ever decrypt the data encrypted with the deleted key.
