Well, my hard drives came in. I basically ordered regular hard drives. Three 2TB SATA 6.0gb. I'm running the latest FreeNAS-8.3.1-RELEASE-p2-x64 on a Dual Xeon 2.5ghz setup with 8GB RAM. I set it up as a ZFS stripe with two drives and the third as a ZFS spare. So I'm good for 1 hd failure. Now to replace my GoFlex "NAS"...time to transfer data.
