ZFS is software. Don't know how ZFS performs, but being software I *bet* it won't write 400MB/s like a hardware controller does. (Ok, 400 at a sufficient high disk number, 6 or 8). I got soft raid 5 on my server and besides that it is troublesome in terms of stability (had at least 6 occurances where a disk flew from the array for no apparent reason, disk checks turned out disk was fine so I re-added it each time) it does little more then 10MB/s writes at cost of many cpu cycles.
