I am looking to set 4 sata drives up in a RAID setup for backup purposes, I am however unsure what raid type to use.
-
I'm not a RAID expert by any means but RAID 0 is not what you should use since you mentioned "backup purposes". RAID 0 uses "striping" only (no parity or mirroring), which is not what you want. You need one of the other types of RAID but, since I'm no RAID expert, I don't want to recommend a specific type.
There are numerous references about RAID on the Internet. Have you searched for them?
-
Yes I have searched the internet but there are so many different opinions, can you have 4 drvies in RAID 0?

RAID 1 - Mirror
Don't know why you need 4 drives for RAID backup.

Check out this article. It may help you make your mind.

@Computer_Commando: When first starting this I thought there was a RAID where you had data over all the drives and if one dies then you just stick in a new one it rebuilds and your data is still safe. Am I wrong?
Hmm does this sound like RAID 5?
-
I guess one of the first questions should have been what are you trying to do and what is your budget? For a home system, raid 5 is over kill, but for a commercial system it may be what you need.

I am just going to get the drives as I get the money, I want a raid system that if one drive dies then my important family documents and movies are still safe, and want heaps of space to stick all my stuff

A RAID array, in any configuration, is a poor substitute for proper backups.
-
yeah but I have a lot of stuff
-
Then you should have a lot of backups...
I have alot of stuff too...

patio = mod?
Well I already have the board the ram and the psu, just have to modify the case a bit.

Not wrong, but maybe misguided. I experimented with RAID 1 for a while.
RAID 1 with, for example, Drive A & Drive B. Drive B is a mirror (exact duplicate) of Drive A, If you lose A, B is always there to take over; you then replace A as soon as you can. Whatever is written to A is written to B, so writes are a bit slower, reads a bit faster, because it could read from A or B. The RAID controller does everything, not Windows. RAID is useful if you're running a server, or a computer that can never, ever be down.
Better to follow BC_P's & Patios's advice.
