RAID lets you cat disks together in a variety of ways: for redundancy,

for extending the sizes, &c. softraid is a new feature just released

in 4.2 that supports on of these ways: 'mirroring'. Mirroring writes

every piece of data to multiple disks, so that if any of them fail the

data is not lost, and the disk can be replaced more or less

transparently.
You'll need to get a bunch of harddrives of different and the same

sizes, and plug them all in. Then follow the instructions here:

It would help to read this too:
