Do not use this for safety/raid1. I have seen several reports that the NVidia software raid wipes out the intact drive on warm boot when the machine reboots with one drive bad. Seems to do a random pick which drive to mirror to which other. gmirror will do fine for raid1, and performs adequately (not as well as Linux software raid1, but probably better than NVidia anyway).
