It depends on what your priorities are.

RAID 0 will give a small increase in read/write speeds and the set up is often used by gamers.

RAID1 often called a mirror configuration is a set up which writes all the information including OS to both discs. In the event of a HD failure the second will still be there to protect the data etc. RAID1 is therefore used by people who require data security from HD failure.

RAID1 will help in the case of a hard drive failure but will not help in the case of something like a massive virus problem, as the second drive is a mirror image of the first, if theres a major software problem on one it will be replicated on the other.
That is why people on the Forum recommend people to get something like the Acronis Drive image Program and use it to do backups to an external hard drive.
Kind of a belt and braces option, if disaster does strike you can reload from the image and only lose what you've done since your last backup.
I have RAID0 and there is a speed boost as it uses the 2 hard drives as 1 and you can get the data off the hard drive faster, the bad point is of course if you lose either drive you lose everything so again an external hard drive is best for backups.
And with either option theres 2 hard drives being used the chances of a hard drive failure is doubled but with RAID1 you can use the other working drive unlike RAID0 where you lose everything.
