I built a NAS server a couple of years back, but have been using it more now that I have switch from FreeNAS to Unraid. I currently am running 5 Drive with one as parity for a total of 19TB usable storage. Also have a 1TB ssd for cache.
I have a MSI B250M VDH motherboard and a G4560 CPU and 16GB of RAM. WIth the increased Plex usage, I am seeing the CPU being a bottleneck. I was wondering from a price to performance ratio, what the best upgrade would be at the moment with keeping the motherboard. My open would be no more than $150 and am not afraid of used.
My uses: Time Machine Backup, Plex, source drive for Lightroom/PS editing.
