RAID Configuration
Below are the different types of a RAID.
RAID 0
breaks the data into blocks which are written to separate hard drives.
Spreading the hard drive I/O load across independent channels greatly
improves I/O performance.
RAID 1
provides data redundancy by mirroring data between the hard drives and
provides enhanced read performance.
RAID 5
provides data striping at the byte level and also stripe error correction
information. This results in excellent performance and good fault tolerance.
RAID 10 uses four hard drives to create a combination of RAID 0 and 1 by forming a
RAID 0 array from two RAID 1 arrays.

Enabling Intel
In Legacy mode, we can change the AHCI mode to RAID mode and disable the Fast
Boot then press Ctrl + I during the POST to enter the Intel Rapid Storage Technology
Legacy mode. However, most newer version of operating systems support UEFI
and the Intel Rapid Storage Technology UEFI mode can still run when the Fast Boot
is enabled. Therefore we recommend that you use the UEFI BIOS for simple and
advanced operations. The following description is based on the UEFI mode.
To enter the Intel(R) Rapid Storage Technology menu
1. Power on and press Delete key to enter BIOS Setup menu.
2. Press F7 to switch to Advanced mode from EZ mode.
3. Go to BIOS > SETTINGS > Advanced > Integrated Peripherals > SATA Mode and
change setting to RAID/ Optane Mode.
4. Go to BIOS > SETTINGS > Advanced > Windows OS Configuration > Windows 10
WHQL Support and change setting to Enabled.
5. Skip this step If you are only using SATA storage devices. If you are using NVMe
PCIe SSDs, go to BIOS > SETTINGS > Advanced > Integrated Peripherals > M2_X
Pcie Storage Remapping and change setting to Enabled.
