Any config I could imagine would be able to stream several videos at once
(even 10Mbit/sec 1080p HD). For very high data integrity and plenty of
performance for streaming a few videos, I'd try:
3 x 9-wide raidz-2
3 x hot spare
For a total of 21 disks worth of usable space. If you need a bit more space,
do:
2 x 14-wide raidz-2
2 x hot spare
for a total of 24 disks worth of usable space.

There are hundreds of possible combinations of 30 drives.
It really comes down to a trade-off of space vs performance vs RAS.
