Proper RAM and drive for ThinkCentre M710Q running Unraid/Plex/-arr (lemm.ee)

For a couple of years, I have been serving Plex to a few friends and family from an NVIDIA Shield Pro on a gigabit fiber. Before that, I served from a Raspberry Pi.

I have basic Linux skills, and my dream is to build a more automated setup. Unraid OS with Plex and -arr apps looks great to a non-expert like me.

So, I just picked up an unmolested original Lenovo ThinkCentre M710Q 7500T with 16GB RAM, and a 256GB M.2. I have a spare 2.5" 2TB Samsung EVO 970 SSD that I could put in it; I also have a 3.5" WD Red 4TB external HDD.

Here are my questions:

  • Do I need more RAM to be able to serve four 1080 streams at once?
  • Should I use the SSD or HDD, or both?
  • Any other advice or suggestions? It's appreciated!

Am I going to run into transcoding issues with 7th gen i5 on several streams?

I have a 4th gen i5 and it can handle about three transcodes concurrently. You should be fine on that, especially if your users direct stream.

all but one of them have modern Roku or Apple TV devices.

These devices should be capable of direct streaming any video format. You'll have to tell your users to change their streaming settings to always play original quality on remote stream. Plex defaults to 720p for remote streams.

should I use the 258GB M.2 already in the box for the config and database, or use the 2TB 970 EVO SSD?

The 256 GB should be enough. My Plex folder uses about 90 GB right now with all the posters and stuff. It's been running on a SATA 256 GB SSD for almost 7 years now. My library is also pretty large, pushing 8 TB total now.

There's no harm in keeping it in.

How is your Plex install so big? My library is like 6x larger and my Plex install lives in a 24GB VM
