If you're looking for a way to have a 3TB RAID5 PV array at power on, I
think the only way to do it is with a hardware RAID controller, such as
an Adaptec 2420SA card

The particular card you choose will depend upon your available bus
slots. Be advised that some users have reported truly awful performance
from individual brands and models (i.e. Highpoint RAIDRocket). You
should have no trouble with any Adaptec card.

Hardware RAID is extremely simple to set up and will present one
physical volume as /dev/sda. Initialization of a RAID5 array composed of
1TB drives might take a l-o-n-g time (many hours). Thereafter, it will
be very fast and should be very reliable if you use quality SATA drives.
