You may get just as much SSD "savings" by putting /var/log and /tmp into a RAM disk. I do this with all of my Raspberry Pi's, since SD cards burn through pretty quickly, and I have several that haven't had their SD cards replaced in a couple years.

I'd like to reduce the wear-and-tear on my SSDs and eliminate the unnecessary metadata writes on my backup media that only slow down the backup process. So I want to add noatime to all my mounts. Is there any downside to this?

At one time I remember atime being useful for tmpwatch, which removes files in /tmp that haven't been accessed in a week or two. But I can live without that feature.
