[LAU] Software RAID for Ardour?

I wondered what the prevalent opinion was about setting up a software raid mirror of two sata drives under Linux LVM. This is on a 3.2GHz quad core AMD system that almost certainly has plenty of free CPU. Will this provide extra disk i/o that could be usefully applied to getting more simultaneous tracks, or will using a software mirror interfere with the RT kernel or cause latency issues/instability somewhere? -- + Brent A.
