Note: Make sure there is a USB drive inserted in the Seagate NAS's USB port if you want to
enable volume encryption. The security key is saved to the drive during the encryption
process.
• Raw Volume: Optionally create a block-level (raw) volume.
Note: Virtualization (iSCSI) requires a raw volume.
• Volume Size: Enter a volume size and optionally set the volume size to be the
maximum.

Understanding RAID

RAID stands for Redundant Array of Independent Disks and is a technology that builds
redundancy into your storage system to help keep your data safe from disk drive failures and
other catastrophes.
RAID comes in many levels, which vary according to the amount of protection they provide
(and how they provide it), and the number of disk drives they support.
By default, your Seagate NAS is preconfigured with a RAID protection level:
• Seagate 1-Bay NAS: No RAID protection available.
• Seagate 2-Bay NAS: RAID 1
• Seagate 4-Bay NAS: RAID 5
