That leads to a lot of stress on the smart sand as it try's to keep your data safe. To use my one raspi-4 with 2 gb of memory as an example, the boot u-sd is a 64Gigger, and the used area is under 8 Gigs. I have, because I and running a buildbot-like environment on it, moved as much of the high traffic write activity to a pair of SSD's mounted over usb3 adaptors, specifically the buildbot runs on a 240G SSD mounted at /media/pi/workspace. Swap is on a 10G partition of a 120G SSD, and I should probably move /var off the u-sd but haven't yet. That u-sd gets about 30 megs of re-write activity a day on average as the last step in my scripts is dpkg installing all of linuxcnc and its docs in English. And its been doing that for about 2.5 years now, starting when the pi was a 1G pi-3 and took most of a day because it was all usb-2 then, lots slower. The only failure was an off brand usb3 to sata adapter, replaced with a startech and zero problems since. The pi4 has a 5 amp supply, heat sinks stuck on it, and an old 12 vlt video card fan running on that 5 volt supply for cooling. And it has a small ups, so it litterally runs from install to install, with reboots by me when libraries need to be reloaded, sometimes months as I have a standby that starts long before the ups times out in 2 minutes, probably the main reason I got the ups for $39.95, that 2 minutes is not adjustable regardless of how light the load is. So I think the best advice is put in a much bigger SSD, so the total capacity used leaves it enough room to keep itself healthy, and forget about it once that has been done. df says its 25% used, so it can degrade and do housekeeping to keep the data safe for several years yet. 64G u-sd's these days are going to be exfat, not well supported by linux yet, so I use gparted to re-format them to ext4, but that may, indeed does, get overwritten by dd when doing the original raspbian buster install. Installing the preempt-rt kernel is more fun as raspbian doesn't support it, so I had to configure, build and invent my own installer. so I did, and pinned it against any attempts by apt to update it. And amanda backs up every byte of it every night.
