In short, when your Plex server is powered by a Threadripper 1950X, the limiting factor quickly becomes your Internet bandwidth, or even the speed of your storage array, rather than your CPU's transcoding horsepower. According to the PassMark database, the average score for the 1950X is 21,941, so we're sitting quite pretty.īased on Plex's guidance, our score means that we should be able to handle at least 10 simultaneous 1080p transcodes, and that's really pushing it since at least some of our Plex clients will be direct streaming or direct playing media with little hit on the CPU. We ran the PassMark Performance Test on our completed build and received a CPU score of 23,602 at stock frequencies. The actual requirements will of course vary based on the complexity of the specific media file and your transcoding settings, but the "2000 per stream" rule is a good place to start. When it comes to measuring streaming performance capability, Plex gives general guidance of about a 2000 PassMark score per simultaneous 1080p stream.
Such speeds are overkill for Plex alone, but they make accessing our PCPer video and data files a much more pleasant experience when combined with the faster network.Īs for our processor, we couldn't be happier with the Threadripper 1950X. That's both locally on the server as well as for large sequential transfers via the 10GbE network. In terms of sequential transfers, we can achieve average speeds of about 640MB/s reads and 720MB/s writes. Our primary storage array isn't going to be the absolute best performer due to its use of slower WD Red drives and an older RAID card, but it's still more than adequate for our needs. So we also have a Synology NAS onsite for local nightly backups (using the handy app Bvckup 2), as well as a Backblaze account for a second cloud-based backup. From there, we used Windows sharing and permissions settings to separate access to the Plex data and our PCPer files. With our drives installed, we used the Areca management interface to configure all of the drives into a single RAID 6 array with a raw capacity of 112TB.
