hardware for home use large storage

[Peter C. Lai]

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?
