Subject:   HPT370 RAID or Vinum?

Hi there,

I am trying to install FreeBSD on a (pseudo-) hardware ATA RAID volume which
consists of two striped ATA disks connected to a Highpoint HPT370
controller.    "Pseudo-" because FreeBSD detects the individual disks
(ad4/ad6) as well as the striped volume (ar0).

Besides the fact that ar0 isn't documented anywhere (except in /dev/MAKEDEV)
and "man 4 ar" gives something completely irrelevant, which one is better to
use:

Highpoint built-in RAID (ar0), or ad4/ad6 striped with Vinum?

I reckon if the RAID functions are implemented in HPT BIOS (in software),
I'll be better off with Vinum.

What do you guys think?

Thanks

John
