Amazon content is around 15000 bitrate with 4K content, in h264 your processor (unraid xeon) will handle it fine with a plex docker. Running HVEC h265 transcode on plex will eat up your current processor, and will result in terrible buffering and delays on the client. Plex addon works fine in kodi, but i mosly use chromecast now or nvidia shield in combination with plex.

I did some initial testing with a older toshiba XG3 256GB (2400/1500MB) as cache drive, and didn't notice any gains on my server compaired to the MX500 (560/510MB). I'm running on a gigabit network and have 5 docker instances including plex (12tb lib, 4 users) and a single VM. (based on my iotop logging of workloads, and my "feeling" playing with plex, did not measure it) If your running 10GBe and more vm's it will probably be a different story. For me the turning point was 2 years more warranty and save 80euro's compaired to the samsung 960evo. What the exact turning point is hard to say, depends on your build.

Pretty insane build, i did the same framing with a build and put in a IKEA besta living room storage. But the disk mounting is a neat idea, quite hard to see on the photo's but did u make custom brackets? Metal backets look pretty stiff. Still wondering about disk vibrations, are the under control?

*snip* Did not get any notifications of a system update on my system.. Weird, indeed needed to update.

For now Kingston VR ECC UDIMM DDR4-2400 8GB Micron, enough in my usecase. Unless i will add more vm's.

I use a Crucial Mx500 500gb running as a cache disk and run my apps and vm's on it with out any issues. Why not use it as a Cache disk?
