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.

Storage drive requirements for RAID levels

Your computer supports the M.2 NVMe (PCIe) solid-state drive

Note: Ensure that your computer has two identical storage drives installed (two hard disk drives, or 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.
