I am no great expert but I run a system using RAID so here are my simplistic
explanations:-

1. RAID cannot operate with only one disk - it requires two or more
identical discs
2. There are a number of versions of RAID each designed for a specific
purpose.
3. RAID 0, also known as a "Stripe" spreads files over two discs and so
allows the PC to read and write simultaneously to both disks. RAID 0 is
therefore designed to increase speed.
4. RAID 1, also known as "Mirroring", automatically keeps a copy of the
first disk on the second disk. RAID 1 is therefore designed for to improve
security because if one disk fails the other keeps working the PC working.

There are numerous other forms of RAID designed to achieve combinations of
the two basic forms but they will require more than two discs.

There is a lot more to RAID but will pause here to see if this helps.

Regards,

Stan
