So you might be fine with an 8port controller card and the onboard connections. However, even if you want 16 SATA connections on one PCIe card, you can buy that. Broadcom SAS 9201-16i is one example. If that is enough bandwidth-wise will depend on your PCIe slot and the drives you're going to attach. I don't see any reason to do hardware raid these days, just a HBA and software raid (zfs or other solutions) should be fine. Everything just my 2=C2=A2 here, of course... cu Gerrit
