Redundant Array of Independent Disks is a way to connect many drives into one pool of storage.
There are many flavors of RAID, the most common are:

RAID 0: 2 or more drives connected for more speed but it's very unreliable (in my experience).
RAID 1: Pairs of drives that do continuous mirror backups for reliability.
RAID 5: I think it uses multiple drives to combine the best of RAID 0 and RAID 1.

RAID is useful mostly in servers. Or a NAS (network attached storage).
I'm sure there are better ways to combine drives in actual servers because RAID is an old standard.
Now that SSD's are fast enough and backups are easy to do, most people don't need it at home.
Every time I have tried RAID 0, it worked but ended up failing and I had to take it apart and restore from back up.

Leave RAID off.
