Hi PerplexedGoat65

it appears, in a practical sense, this means to mount the second drive, and then bind them in ClearML’s configuration

Yes, the entire data folder (reason is, if you loose it, you loose all the server storage / artifacts)

Also, thinking about Docker and slower access speed for Docker mounts and such,

If the host OS is linux, you have nothing to worry about, speed will be the same.
