RAID 1 and External Hard Discs Possible?

[Beaverfish]

Ok here goes (This is my first ever thread) go easy on me.

I have a MBP (see signature) and two Freecom 500GB USB external Hard Discs. Is it possible to somehow set up these two HDDs in a RAID 1 configuration under OS X. The reason for this is that right now I have a large collections of films on the one of the HDD and would hate to loose them all if the disc failed.

You can, and there are even a few tutorials online for setting up RAID 1 between system boot disk and an external drive. I would suggest just manually backing up, though. It's more straightforward.
