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.
Configure RAID with RAIDXpert2 Configuration Utility
If your computer comes with the RAIDXpert2 Configuration Utility , you can follow the sections below to
configure RAID.
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:
a. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
b. Select Devices ➙ Storage Setup ➙ Configure SATA as (AHCI/RAID).
c. Select RAID.
• NVMe RAID mode:
a. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
b. Select Devices ➙ NVMe Setup ➙ NVMe RAID Mode (Enabled/Disabled).
c. Select Enabled.
2. Press F10 or Fn+F10 to save the changes and exit.
3. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
4. Select Devices ➙ RAIDXpert2 Configuration Utility to select drives and configure RAID.
Storage drive requirements for RAID levels
CAUTION:
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. 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
– Provide the highest performance but no data redundancy. Data in the array is striped (distributed)
across several disks.
