I'm setting up my new FreeNAS box and have been reading everything I can consume, watching videos, etc and I'm while I think I understand that there is a performance hit as you add parity, I'm not sure it's applicable to the performance requirements for my situation. I have 5 X 2tb drives (I actually have 6, but I want to import a volume from an older, failed FreeNAS box and only have 6 SATA ports on the mobo so I think I'm stuck leaving one port unused, hence 5 X 2tb) and this box will be used mainly for Plex, some windows data storage and maybe some photo archives from my Mac. I guess the question is will I see much of a difference in performance between RAIDZ2, 3 or a set of mirrors when we usually have just one instance streaming from the NAS?
I can't see us ever needing more than 2T of storage as our current datastore is around 800Gb and there's at least 30% of that that can be removed.
I'm leaning towards RAIDZ3 for the redundancy, but am open to the more experienced of you to chime in.
For reference, my previous box was a 6-7 yr old desktop with a single 2T drive in it and we never saw any issues with streaming, etc. The new box is exponentially more powerful so I'm guessing this is a moot point.
Thanks again for all the help.
