How to Build an Encrypted RAID Volume on Your Thecus NAS

How to Build an Encrypted RAID Volume on Your Thecus NAS
Thecus’ AES 256bit RAID Volume Encryption feature
allows users to encrypt RAID volumes on their Thecus
NAS with a writable USB disk. Once a RAID volume has
been encrypted, no one will be able to access their NAS
to retrieve data or modify settings without the USB disk
containing the encrypted key; therefore, users’ precious
data will be 100% secure even if someone has stolen
their hard drives or the even their entire NAS server.
Applicable Models: N4200, N0503, N5500,N7700 Series, N8800 Series, 1U4600R /1U4600S
