Customizing Your Seagate® NAS Understanding RAID

Seagate Business Storage NAS Administrator Guide 20

• Disk Selection: Select one or more hard disk drives for your volume.

The following table provides information for all Seagate NAS models. You may not have all

disk configurations available for your new volume creation.

• Volume Encryption: Optionally enable volume encryption.

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
