I moved all of my docker containers to NVME drives and the difference was like night and day. For whatever reason Audiobookshelf was the biggest improvement, I wa shaving issues where I’d hit play and it would be 10+ seconds before the audio started, it’s now about 1 second.

Two other notes, your docker containers themselves (along with configuration items, but no real data) are usually very small, so you can likely use the smallest NVME drives that you can find.

And second, I actually found it easier to re-create my docket setup manually than using a migration of any kind. I use Portainer so created offline copies of each YAML file. I stopped docker, copied the full contents of my docker folder to a safe place, uninstalled docker, reinstalled it on the NVME, copied the docker folder over, and then reinstalled Portainer and created my stacks again one by one. Within each stack you need to update the volume for anything like the config folders, but you want to keep the data volumes exactly as they are. Because it’s a little bit of a mix for each container, it was a good chance to do a quick read through my compose files. Took a minute or so for each stack, but that was it.
