if it is RAID10 i assume you have 4 disks.
trying to replicate behaviour from FreeBSD 8.3 (array created through
RAID BIOS, seen as a device in OS).
BIOS raid is not compatible with gmirror RAID.
backup and restore.
Actually i would recommend creating it as two RAID1 (gmirror) devices and
spreading data. it is safer and..if you can spread data well... faster.
"BIOS" RAID usually use far too small block sizes, to be "better" on
windows benchmarks that shows linear read speed.
except specialized uses it is no improvement under unix.
What you need is to spread DIFFERENT I/O operations from different task to
different heads.
