I have been using gmirror + gstripe (RAID10) to serve /home on a busy 
multi-user system/NFS server since 5.3-RELEASE/amd64 with zero problems. 
I use the onboard ahd on a Tyan 2882; half of each gmirrored pair is on a 
different channel, then gstriped across the pairs.

gmirror	A	B	C	D
ahd0	A0	B0	C0	D0
ahd1	A1	B1	C1	D1

gstripe A+B+C+D

Caveat emptor: I have not had any drive failures in this configuration.
