Chapter 5. RAID
What is RAID
Redundant Array of Independent Disks (RAID) is a technology that provides increased storage functions and
reliability through redundancy. It also can improve data storage reliability and fault tolerance compared with
single-drive storage systems. Data loss resulting from a drive failure can be prevented by reconstructing
missing data from the remaining drives.
When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID
array. This array distributes data across multiple storage drives, but the array appears to the host computer
as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited
I/O performance, because several drives can be accessed simultaneously.
Select RAID mode
You can select the SATA RAID mode or NVMe RAID mode to configure RAID with RAIDXpert2 Configuration
Utility.
1. Do one of the following to select the SATA RAID mode or NVMe RAID mode:
• SATA RAID mode:

RAID Levels
CAUTION:
• Only one redundant RAID array is supported by AMD-RAID. RAID1, RAID5, and RAID10 are all
redundant arrays.
• The AMD-RAID does not support more than eight arrays, including Non-RAID array.
• Multiple operating systems are not supported on AMD-RAID Array. If the system is booted from an
AMD-RAID bootable array, the first array in the Arrays section must be the bootable array. The
system boots only from the first array in the Arrays section. Refer to “Configure RAID with
RAIDXpert2 Configuration Utility” on page 42 to find the first array by viewing array details and
checking the array number.
Your computer supports the following RAID levels:
• RAID 0: striped disk array
