My work laptop has 0.5T SSD and it's 90% full. Turns out VMs, large repos, and OS projects are big. I know there are some large docker images too.
Just recently I found that I had like 100s of GBs used up on my hard drive because I'd installed and used podman for a while and it's image store was separate and just... sitting there, long after I'd moved back to docker for reasons.
