Best answer: No, the ASUSTOR AS6508T is not a good NAS for Plex, simply because its Intel processor is too weak for transcoding.

Jul 12, 2020 For Plex to see the content on that other share/drive, you need to make it locally available to the NAS’ file system. Here’s a description from Asustor on how you can mount such a remote drive using NFS. I suppose their knowledge base has similar articles for other protocols if you’re e.g. ASUSTOR does not offer any warranty for Plex software and does not take any responsibility for customer use of Plex software and services. Thirty day free trial has no cash value. Offer subject to change without warning. Plex and ASUSTOR reserve the right to rescind this offer at any time for any reason necessary.

• Solid NAS overall: ASUSTOR AS6508T ($1,097 at Newegg)
• Better for 4K on Plex: Synology 1019+ ($650 at Amazon)

Not the best from Intel

Intel's Atom C3538 (clocked at 2.1Ghz) isn't a particularly powerful processor. It's 64-bit, has multiple cores, and doesn't have an issue with maintaining its rated clock speed, but there simply isn't enough performance here for 4K on Plex. Unfortunately, the ASUSTOR AS6508T has this processor, making the NAS for Plex a hard sell.

The issue with the ASUSTOR AS6508T is that it's an incredibly capable NAS aside from the CPU. I'm talking dual 2.5Gb and 10Gb LAN ports. That's madness for a consumer-grade NAS for the home and small office, but all these features are focused on file storage as opposed to media consumption.

One should aim for an Intel Celeron CPU at the very least. The latest Celeron processors in NAS models are capable of transcoding even 4K content without much of a stutter, though that's a single stream mind you. This isn't something you can hope for with NAS models that rock six bays or more. The majority of them come with this lesser CPUs.

Choosing the right NAS for Plex

Picking up a better-equipped NAS for Plex is a must if you plan on streaming plenty of 4K content. Pick a smaller NAS with up to 6 bays, and you should be able to score a decent Intel CPU. Something like the Synology DS1019+ would be a better fit. You only sacrifice three bays, still allowing you to install plenty of storage capacity.

This NAS, for instance, has an Intel Celeron J3455 CPU (clocked at between 1.5 and 2.3 GHz) and is a much better fit for Plex playback. It even supports 4K transcoding with positive results. This NAS also supports expansion, so don't worry if you feel the five bays a little restricting to begin with.

Asustor Nas Setup

You're going to need the ASUSTOR AS6508T to upgrade the RAM. If you're looking for an 8-bay NAS with M.2 SSD slots and an Intel processor, this is a solid example. It's a killer mid-tier NAS for the home or small office.

Synology 1019+

The Synology DS1019+ is better suited to Plex media simply because it has a far better Intel processor with better hardware transcoding support.

Using as Asustor AS5304T and all videos 1080P through 4K lag while playing on the browser-based Plex Media player - play just fine when playing the raw video file even from the NAS. There’s massive stutter, skipping, and artifcating.

Using 2x 6TB Ironwolf HDDs. 500 Mbps internet speed and my router is the Nighthawk AX12 capable of enormous throughput.

What’s the problem? It seems its an issue with the player itself.
