Craig,
3. I do not think you will get much dedupe on video, music and photos. I would
not bother. If you really wanted to know at some later stage, you could create
a new file system, enable dedupe, and copy your data (or a subset) into it just
to see. In my experience there is a significant CPU penalty as well. My four
core (1.86GHz xeons, 4 yrs old) box nearly maxes out when putting a lot of data
into a deduped file system.
If you want to know what your potential savings for dedup are you can
use zdb(1M) to calculate that:
# zdb -S <poolname>
