December 9, 200619 yr I'm looking at some possible options for when I eventually buy my new system. In my current system, I use 2 SATA drives configured in a RAID 0 stripe, but this statistically doubles the chance that I will lose the volume. To get some fault tolerance (and throw in another spindle) I was considering a 3 drive RAID 5 configuration in my new system, but hadn't heard much about anyone using an array with Flight Sim, probably due to cost and available drive bays. Anyone using a RAID 5 array with Flight Sim? I know that each write to a RAID 5 array incurs a 4 IO write penalty, but reads don't suffer any penalty. Does anyone know if RAID5 read IO causes any extra CPU overhead, or is it only write IO that adds to CPU usage due to parity calculation when writing?
