RAID (for Intel models only)
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.
Storage drive requirements for RAID levels
Your computer supports M.2 Non-Volatile Memory Express (NVMe) solid-state drive.
Note: Ensure that your computer has two identical storage drives installed (two M.2 NVMe solid-state drives
with the same capacity) for supported RAID levels. If only one drive is installed, or two different types of
drives are installed, the following information does not apply.
Your computer supports the following RAID levels:
• RAID 0: striped disk array (missing data resulting from a drive failure cannot be reconstructed)
– Consist of two identical storage drives
– Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB
– Better performance without fault tolerance
– Higher risk of data loss resulting from a member drive failure compared with non-RAID configuration
• RAID 1: mirrored disk array
– Consist of two identical storage drives
– Improved reading performance and 100% redundancy
Enter the Intel RST configuration utility
1. Ensure that RAID is enabled in the UEFI BIOS menu:
a. Restart the computer. When the logo screen is displayed, press F1 to enter the UEFI BIOS menu.
b. Select Config ➙ Storage ➙ VMD Controller ➙ On.
c. Press F10 to save changes and exit.
2. Restart the computer. When the logo screen is displayed, press F1 to enter the UEFI BIOS menu.
3. Select Config ➙ Storage ➙ Intel (R) Rapid Storage Technology and then press Enter.
The Intel (R) Rapid Storage Technology window opens and the following options are displayed:
• Create RAID Volume: Create a RAID volume. If no internal storage drives can be used, this option is
not available.
• RAID Volumes: Confirm the information of the created RAID volumes.
• Non-RAID Physical Disks: Confirm the information of all non-RAID drives.
4. Press the up and down arrow keys to select an option. Press Enter to enter the menu for the selected
option. Press Esc to exit the Intel RST configuration utility.
