Sata Legacy vs AHCI vs Raid 0 for pfsense?

  • Hello,

    I want to install pfsense. In Bios there is Sata Legacy Support, AHCI Support and Raid Controller.
    I have 2 Hdds. I wil install pfSense with ZFS mirroring. I want to know which one should I choose? Legacy, AHCI or Raid 0?

    I would choose AHCI there if you're going to use a ZFS mirror.

    The hardware RAID controller may or may not be supported but they do relatively often give problems. I would avoid that and use a ZFS mirror instead if you can.
