You are assuming wrong. It is software RAID, just like almost all on-board RAID implementations (and most of the cheaper add-on RAID cards.) RAID that is supported in the BIOS have one advantage over other software implementations, and that is that you can boot from all supported RAID configurations, which is not always the case otherwise. > > Would I be better off just using two disks and mirror them in software > raid (zpool) or using the Intel hardware-ish raid and then zfs the raid? > > box has 2G of ram, and a pair of 250G sata 300 drives. > > clues appreciated. ZFS still feels a little bit too experimental for my own tastes (although opinions differ on that matter), but apart from that ZFS is probably the best solution. -- Erik Trulsson ertr1013@student.uu.se
