Please describe your issue in as much detail as possible:

The steam client in SteamOS (in my case, in the Steam Deck) caches downloads of games instaled in the main SSD into the MicroSD. I attach a screenshot of it happening while updating Helldivers 2 (prefix 553850), which is installed in the SSD:

In this case I had around 40GB of free space in the SSD and around 130GB in the microSD.

I think that this is unacceptable behavior. Not only it makes updates terribly slow, but it significantly reduces the life span of your microSD.

Steps for reproducing this issue:

  1. Launch steamos with a microsd plugged in and properly mounted and formatted
  2. If an update of some game starts, there is a chance that it will be cached in the MicroSD
