I've decided I want to do more with the box but keep using zfs (or rather raid z) so have decided on OpenIndiana as the OS.
The MB is an Asus m4a88td-m and all 6 onboard SATA are used. I want to install the OS in RAID 1 on 2 extra SATA II drives 160GB (3 Gb/s Seagate Barracudas) that are spare.
The 1 x PCIe 2.0 x16 and 2 x PCIe 2.0 x1 are empty.
Can anyone recommend a PCIe to SATA card that'll give good performance and RAID 1?
Or should I be putting the intended OS disks into the onboard SATA and move 2 of the 2TB WD Greens (wd20ears-00mvwb0) onto the card, thereby not need the card to do any RAID?
