Hello,   My SSD cache has about 2TB written in two weeks only. That feels much for a 250GB ssd. No mover is used. Writing files to array directly. The ssd is used for the docker img and appdata. ~1 TB/week gives me about 2.8 years before hitting the TBW limit of 150TBW for warranty. 5 years or 150TBW, what comes first (Samsung SSD 860 Evo). I want to dig deeper. How can I see what it is, doing lots of writes to the ssd? Edit: I answer myself. "iotop" installed using Nerd
