Using TrueNAS as a reliable array and transcoding [nVidia-accelerated, Premiere proxies] ..?

[TrumanHW]

Is there an (ideally, GPU (nVidia if possible) accelerated) 'jail' to create Premiere Pro proxies, ..?

Or would I be better off looking at ZFS over Linux ... or UnRAID (does it checksum and scrub data like ZFS..?)

Plex..? I've heard "Emby" mentioned but don't know if it's a jail or what.

Thanks!!!
