That's faster than just about anything I have at home. So you should be fine. It should be good enough to serve as primary media center storage even (for retrievals, anyway, probably a tad bit slow for live transcoding).
Also does anybody know if benching dd if=/dev/zero onto a zfs volume that has compression turned on might affect what dd (which is getting what it knows from vfs/vmm) might report?
