From personal experience and benchmarking in this area in the past, I would not recommend trying to run with aggregates over 90% full where you need optimal performance. I run a lot of CIFS shares on filesystems that are a little too full, but you will experience a significant performance degradation when you cross the 90% barrier. For things like video streaming, such an occurrence could be very disruptive.
If the older data is not so active and premium performance isn't a requirement, you might get some saving out of deduplication, but I'm not sure how much, if any savings, can be achieved with video formats...
I hope that the aggregates will not exceed the 90% mark. But what about the volumes?
