In your case, performance will be almost irrelevant.  Because even with a single disk, you would be able to do over 1Gbit/sec, but with your raidz or raidz2, you'll be able to go much faster.  But I bet the network you're connected to is 1Gbit or slower...  And...  Even if you're streaming the full BluRay disc or something, you only need about 8Mbit.  

So your demands will be far lower than even the lowest performance setup you could imagine creating.
