Even the Windoze-guys tell us that they don't trust it. So we settled for RAID1 via gmirror. MatrixRAID is a scam, if you ask me - like all the other BIOS-RAIDs we have had the displeasure to see over the years. I really thought it was common knowledge. But now that you mention it, I can't find a reference to this in the FreeBSD docs (at least not with a quick look). The handbook-example uses RAID1, though.
