This file you may get sometime on the Motherboard drivers.
RAID used to be something you see for servers only. Now, most home desktops are capable of it with integrated RAID controller cards.
It’s designed for two things: Backup and performance.
If one hard drive fails (common in servers which run constantly), another one (with the same exact data-called a mirror) can turn on instantly and the end users will never notice that the there was a problem.
A server that gets heavy user traffic may need the speed of multiple HDs to be able to satisfy the needs of all those computers without slowing down. Multiple HDs means multiple read/write heads that can access different parts of the file (stored across all HDs) simultaneously, speeding up the time it takes to get the data to the user.
There are multiple configurations of RAID which allow for either maximum backup capabilities, performance, or a combination of both in varying degrees.
the RAID Controller allows you to either hook up multiple drives to make them run faster and give more speed(RAID 0)
Or work as a back up hard drive that copies everything the main hdd does. (RAID 1) there are other RAID set ups both those are the most popular.

RAID allows you to run multiple hard drives together in different configurations either for better performance, data mirroring, etc.
