The two options RAID you describe are used for differeent purposes.
.
RAID-0 is generally used for speed (or throughput if you want to be picky). If you are running an application that wants to write to the disk rapidly (say graphics/movie generation) you would probably make use of RAID-0. Even playing high end games would benfit from RAID-0 as they get data off the disk quickly.
.
RAID-1 is used for data safety. If one of your disk fails, you are not impacted as all of the data is on the other disk. Thisis usually used for data server systems. (And behind the scenes the 2nd disk is replaced during system maintenance.)
.
If you are doing backups I can't see needing a dedicated RAID-1 on a home system. If you are flush with cash, there are RAID options which combined both RAID-0&1 for the best of both worlds; but then you have to get a high end RAID controller to handled the data traffic or you lose the spped advantage.
.
To make the change you alter setting on your RAID card. (Not the computer BIOS.)
