My backend runs 6  750GB SATA drives for storage, configued as 3  1.5TB 
raid 0 arrays, since I'm most concerned with maximizing storage space. I 
have run XFS on my storage drives for many years, with nary a hicup.

My system disk is a 40 GB IDE drive that shares the cable with a BluRay/HD-
DVD drive. This system disk is about twice as big as it needs to be. It runs 
EXT3.

Both the OS and MySQL are on the system disk. The storage arrays have all 
the recordings, music, RIPs.

It's dedicated to being a MythTV backend/frontend only, as I have another 
server on my home network for everything else. My system has been rock-
solid for years. 

In my case, on my hardware, this configuration has been very well-behaved.

YMMV
