Okay, today I got my tax return, a wonderful 800 Euros and I just went and got myself another 40gb HD to play around with RAID. And I was wondering..

a) How does one go about doing this? - Ender tells me that kernel software RAID will be much faster than my Hacked Promise RAID controller, so I would like to go with that.

b) How to NOT mess up my perfect LFS system when I go and do whatever it is I do ?
(A full backup on my server is possible if that's easier.)

c) One would like to go RAID 0+1 (if I recall the name correctly) - 2x40GB = 80gb FFM (Fucking Fast Mode )
