3.5 RAID configurations The motherboard comes with the AMD RAIDXpert2 Technology that supports Volume, RAIDABLE, RAID 0, RAID 1, and RAID 10 (depends on system licensing) configurations. For more information on configuring your RAID sets, please refer to the RAID Configuration Guide which you can find at https://www.asus.com/support, or by scanning the QR code. RAID definitions Volume provides the ability to link-together storage from one or several disks, regardless of the size of the space on those disks. This configuration is useful in scavenging space on disks unused by other disks in the array. This configuration does not provide performance benefits or data redundancy, disk failure will result in data loss. RAIDABLE arrays (also known as RAID Ready) are a special type of Volume (JBOD) that allows the user to add more storage space or create a redundant array after a system is installed. RAIDABLE arrays are created using Option ROM, UEFI, or rcadm. The ability to create RAIDABLE arrays may vary per system. RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a sustained data transfer rate, double that of a single disk alone, thus improving data access and storage. Use of two new identical hard disk drives is required for this setup. RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to a second drive. If one drive fails, the disk array management software directs all applications to the surviving drive as it contains a complete copy of the data in the other drive. This RAID configuration provides data protection and increases fault tolerance to the entire system. Use two new drives or use an existing drive and a new drive for this setup. The new drive must be of the same size or larger than the existing drive. RAID 10 is data striping and data mirroring combined without parity (redundancy data) having to be calculated and written. With the RAID 10 configuration you get all the benefits of both RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing drive and three new drives for this setup.

RAID configurations
The motherboard comes with the AMD RAIDXpert2 Technology that supports Volume,
RAIDABLE, RAID 0, RAID 1, and RAID 10 (depends on system licensing) configurations.
RAID definitions
Volume
provides the ability to link-together storage from one or several disks, regardless
of the size of the space on those disks. This configuration is useful in scavenging space on
disks unused by other disks in the array. This configuration does not provide performance
benefits or data redundancy, disk failure will result in data loss.
RAIDABLE
arrays (also known as RAID Ready) are a special type of Volume (JBOD) that
allows the user to add more storage space or create a redundant array after a system is
installed. RAIDABLE arrays are created using Option ROM, UEFI, or rcadm.
The ability to create RAIDABLE arrays may vary per system.
RAID 0 (Data striping)
optimizes two identical hard disk drives to read and write data in
parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a
sustained data transfer rate, double that of a single disk alone, thus improving data access
and storage. Use of two new identical hard disk drives is required for this setup.
RAID 1 (Data mirroring)
copies and maintains an identical image of data from one drive to
a second drive. If one drive fails, the disk array management software directs all applications
to the surviving drive as it contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the entire system.
Use two new drives or use an existing drive and a new drive for this setup. The new drive
must be of the same size or larger than the existing drive.
RAID 10
is data striping and data mirroring combined without parity (redundancy data)
having to be calculated and written. With the RAID 10 configuration you get all the benefits
of both RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing
drive and three new drives for this setup.
