Call me pedantic and dismiss it… But at least we’ve discussed it 
Problem
I observed that Obsidian (at least on macOS) writes changes to files to the file system about every second. Although only a couple of characters has changed most of the time, the whole file is written to the file system.
I wonder if this contributes to heavy SSD wear.
Reasoning
Investigating something entirely different I came across this article from Apple’s developer support. It targets iOS, but IMHO applies to macOS as well.
It states among others:
iOS can only write to the same region of SSD a limited number of times before the disk wears out. The more writes an app makes, the faster it wears the drive.
Changing a serialized document requires rewriting the entire file, which increases the latency of the operation and the wear on the device.
Solution
I can think of a number of solutions:
- Larger write intervals
- Manually triggered writing to disk (CMD+S)
- Auto save only on lost focus event
