  1. Someone should really make a PSA for this. I purchased a brand new ssd in January, 163 TBW on it now. Like others have mentioned earlier, iotop shows loop2 is constantly writing to the disk. Using df -kh shows /var/lib/docker is mounted on loop2. I have a 5 disk btrfs encrypted array with a non-encrypted btrfs cache disk (Samsung EVO 860 1TB). Running several dockers, mainly for web hosting (traefik, cloudflare, organizr, etc.) and data storage (ms SQL Server, influxdb). No VMs. Below is a slightly modified/simplified version of a script to calculate drive TBW and health %. Source here #!/bin/bash ### replace sdg below with label of drive you want TBW calculated for ### device=/dev/sdg sudo smartctl -A $device |awk ' $0 ~ /Power_On_Hours/ { poh=$10; printf "%s / %d hours / %d days / %.2f years\n", $2, $10, $10 / 24, $10 / 24 / 365.25 } $0 ~ /Total_LBAs_Written/ { lbas=$10; bytes=$10 * 512; mb= bytes / 1024^2; gb= bytes / 1024^3; tb= bytes / 1024^4; #printf "%s / %s / %d mb / %.1f gb / %.3f tb\n", $2, $10, mb, gb, tb printf "%s / %.2f gb / %.2f tb\n", $2, gb, tb printf "mean writes per hour: / %.3f gb / %.3f tb", gb/poh, tb/poh } $0 ~ /Wear_Leveling_Count/ { printf "%s / %d (%% health)\n", $2, int($4) } ' | sed -e 's:/:@:' | sed -e "s\$^\$$device @ \$" | column -ts@
