easy peasy:

- backup existing LE config
- install new SSD
- restore ChromeOS using recovery media
- re-install LE using EZ Setup Script
- restore LE backup

You're perfectly safe to assign as much space to LE as you want, leaving ChromeOS 10GB or so (just use the max the script recommends). I run a similar setup re: mysql on Synology over LAN and have zero speed issues. If you're running the Kodi UI at 4k, then that's definitely going to be sluggish since max refresh there is 30Hz at 4K. I'd recommend running the Kodi UI at 1080p/60 and using refresh-rate switching on start/stop to let Kodi output film content at 2160p24 as needed. No need to upgrade IMO unless you want 4K UI and/or HEVC playback, but even then I'd wait as there's no perfect 4Kp60/HEVC/HDR box yet

Great info, thanks again Matt. I'm not running the UI at 4k so that isn't the issue with sluggishness and it was present before I upgraded to the newer TV. Looks like it is something else in my setup. I will see how it runs with the new SSD and go from there, good to know there is no need to upgrade anything else for now...
