You do not normally have that much bandwidth even in a modern machine.
Typical bandwidth for the northbridge/southbridge connection is 1-2 GB/s
for most machines sold today. (For example just about all machines with
a recent Intel desktop chipset. The connection between north- and south-bridge

actually there is not much need to have it for RAID-0/1/10 where there is
almostnothing to process.
For mirrors it can actually be a big win with hardware support.
If you use software RAID then you will have to perform each write twice
(once to each disk),
in parallel

The pair of ex-RAID disks are ad1 and ad2 and obviously are no longer
a raid pair, yet 'something' is telling the ar() driver to try and
pair them and failing because there is no raid hardware in that box.
there are no "raid hardware" on most devices. it's just marketing hype.
actually there i
