/var/cache/apt/archives can chew up some real estate.

On one of my machines, I use a 64gig SSD for /, /tmp and /home are on
part of a platter.
Can't remember what problem I had, but I couldn't move /var of an
operational system to a platter, so it's living on the SSD. Plenty of
room on the HD and SSD.
My main reason I wanted /var off was not that important, it was largely
to get off some transient files, like apt files and logs. With limited
writes, it might cut the drive life by a couple of months at most.
