Truer words were never spoken. It's JUST TV. 

My MythTV backend was until recently running EVERYTHING including the 
database and the OS (all but the kernel and boot files) on a single 
raid0 array, just so that I could have as much contiguous storage 
space as possible. How dangerous is that? People on this list told me 
that I couldn't possibly get the performance that I claimed with the 
OS, database, AND recordings all on the same drive (actually array) 
but I routinely recorded 3 HD OTA programs and could stream 2 at the 
same time (never tried to stream more than 2 while recording 3) and 
never had a hiccup.

My point is, putting everything on a raid0 made up of 5 garden-
variety 750's (would have had 6 but I couldn't figure out how to 
stuff another drive into the box) means I had 5 times the possibility 
of a total system failure due to a failed drive, but so what? It's 
JUST TV!
