The WD 3TB Red drives in general are highly appropriate for software RAID (ZFS and Linux RAID such as MD600). Their factory went through a bad patch (last year I think?) when the RED drives were mistakenly loaded with WD Green firmware, which *may* introduce reliability problems and premature aging with software RAID schemes. The firmware can be patched though it requires a Linux machine and some software or booting into DOS on a Windows architecture machine. PM me if you want more information about this.
