Why even bother with the LSI card at all?
That board already has 6 SATA slots - depends how many disks you want
to use of course. (5 HDs + 1 DVD drive?)
Plus two SATA drives in a gmirror for the base OS, and one optical. I
want a minimum of 8 slots.
I think that 2 HDDs in gmirror just for base OS is an overkill if you
want this machine as home storage. You will be fine with booting the
base OS from CF card or USB stick. (and you can put two USB flash disks
in gmirror if you want redundancy)
This way you will save some money, SATA ports/cards and if you will use
some kind of fast and big USB stick, you can use part of it as L2ARC for
speeding up read performance of ZFS

I have my backup storage machine booted from USB stick (as read-only
UFS) with 4x 1TB HDDs in RAIDZ. It is running one and half year without
problem.
I agree. However, the machine will be primarily storage, but it will
also be running PostgreSQL and Bacula. I already have smaller unused
SATA drives laying around here.
Thank you
