I know, I've been thinking about that too, but so far under my ten years at
this department the issue of getting lost data back to the user fast is
principal. OTOH, should the raid0 die unexpectedly I'm in trouble anyway. 
        For the Windows-clients, I have a Volume Shadow Copy-solution in
hand as a temporary middle-solution. The linux-clients, the data is also
available on the client side for a while. 
        The users know to backup their most important docs to sticks and
whatnot. Our backup-solution is the last resort only really.

FWIW, I've run raid0-arrays for quite a while now, w/o too much problems.
Especially the linux-variety of software raid0 has been pretty impressive
IMO.

The clients and backup-server are located on separate locations, and we
consider that secure enough. I've been running BPC for a couple of years
now, and still nobody has asked for a file-restore. 8-/

Anyway, I believe I'll lose too much space with a raid10-solution. And
again, I know of the risk with raid0. The bigger they get, the higher the
risk is for a failure sooner or later.
