Yeah, this IS one of the issues around flash/SSD storage... They run fast and wear out faster.

My suggestion for a Raspberry PI is to use a USB disk and use the info at this link:

https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md

That will allow you to run Devuan from a USB drive attached to the PI and completely avoid the whole flash memory issue.
