November 26, 20196 yr To clarify question: I am using Transmission container, which is using mapped volume /downloads <--> /mnt/disks/downloads for transferred data. docker.img is on SSD cache drive, /mnt/disks/downloads is unassigned HDD. In Transmission I see cumulative DL/UL data size of ~10 TB, which, if my calculations are correct, corresponds to cache SSD S.M.A.R.T. attribute "246 Total host sector write" which is 21877021800. SSD Sector sizes: 512 bytes logical, 4096 bytes physical. In addition to Transmission's data I also saw docker.img size increase when I uploaded some large files (couple of GB) to Nextcloud.
November 26, 20196 yr Data is only written to the docker.img file if the path the container is writing to is NOT mapped to an external location.
November 27, 20196 yr Author I have mappings for all containers configured and this happens when I upload ~5 GB file to Nextcloud: Before upload: Seconds after finished upload: After 10-20 seconds values return to same state as before upload. Is this container specific (if so, I will ask in NC thread) or could be something wrong with my docker configuration? My unRAID version is 6.6.6

My unRAID version is 6.6.6 Chances are that Nextcloud has a location where it uploads files to before moving the file to its final location. If that is the case and that location has not been mapped externally then that would explain what you are seeing.
