Mostly you only need to read from the os pool, so you will still benefit from the speed of 2 drives with a mirror. If you are worried about db writes etc, then partition up the drives and have another pool for the db with the zpool configuration you want. Better still put it on its own spindles. Use tmpfs for tmp space etc and you could put swap on the striped pool as well. Just keep the os pool as a mirror its far safer. I also set copies=2 on the root zfs fs as well just for a bit more paranoia
