Crash report sizes are dependent upon RAM in the system I believe. So the less RAM you have, the smaller you can make the page file before it gives you that warning. But this is only if you really care about crash reports/crash dumps. If you don't care about them, you can set the page file size to whatever you want.
Just an offhand topic because I've seen it come up... Should the page file be on the SSD? And the answer is basically yes it should be
Yes. Most pagefile operations are small random reads or larger sequential writes, both of which are types of operations that SSDs handle well.
In looking at telemetry data from thousands of traces and focusing on pagefile reads and writes, we find that
- Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1,
- Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB.
- Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size.
In fact, given typical pagefile reference patterns and the favorable performance characteristics SSDs have on those patterns, there are few files better than the pagefile to place on an SSD.
