Hi Joshua,
These are the settings I would use for a good all-round mount of Google Drive on Windows with 400 GB available for caching in D:\temps:
rclone mount --network-mode --buffer-size=0 --vfs-cache-mode=full --vfs-cache-max-age=720h --vfs-cache-max-size=400G --drive-pacer-min-sleep=10ms --drive-pacer-burst=200 --cache-dir D:\temps crypt: T:
I think it will be good for Plex and Emby too, so I suggest you try it and let me know how it compares to your current command. Note: It may be a little slower initially when loading your most used files into the cache.
Here is a variant using only 5 GB caching in C:\temps in case you want to try it before adding the extra SSD disk:
rclone mount --network-mode --buffer-size=0 --vfs-cache-mode=full --vfs-cache-max-age=720h --vfs-cache-max-size=5G --drive-pacer-min-sleep=10ms --drive-pacer-burst=200 --cache-dir C:\temps crypt: T:
The suggestion is based on this post:
