What is raid mode in bios?

The RAID (Redundant Array of Independent Disks) mode in BIOS is a storage technology that allows multiple hard drives to be linked together to form a single storage unit. This can improve performance, provide redundancy in case of disk failure, and increase storage capacity.

There are several RAID levels that offer different benefits, including increased speed, data protection, or a combination of both. Some common RAID levels include RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), and RAID 10 (mirroring and striping).

To configure RAID in BIOS, you typically need to enter the BIOS settings during the computer's startup process and navigate to the storage or SATA settings. From there, you can select the RAID level you want to use and configure the individual drives to be included in the RAID array.

It's important to note that setting up RAID in BIOS will usually require you to reinstall your operating system and any other data on the drives, so it's recommended to back up your data before configuring RAID. Additionally, not all motherboards support RAID, so you'll need to check your motherboard's specifications before attempting to set up RAID in BIOS.
