There shouldn't be any particular difference between the two - one is obviously easier to reach than the other.

If the 16 port controller has a JBOD mode, use that and use mdadm. Splitting between some MB SATA ports, some on a card may not be efficient.

Does anyone here have experience doing that? "Motherboard RAID" is not portable - mdadm is at least as efficient. On the one machine I have that has "motherboard RAID", it's effectively something like mdadm but writes some signature to the disk that means it can only be read by that software. A "proper" RAID controller has large amounts of RAM, battery backup - they generally cost $$$ > > Thanks Tomas > Cheers, Gene Heskett. > -- All the very best, as ever, Andy [amaca...@debian.org] > "There are four boxes to be used in defense of liberty: > soap, ballot, jury, and ammo.
