Reducing this time does sound warranted. But there might be some other
places as well where firefox is doing a lot of disk activity for no
reason, hurting SSDs and power use.

On my system, sessionstore.js isn't being written to if I'm not loading new pages/tabs in the browser. However, places.sqlite-journal is being written to very frequently, even if the browser is just sitting idle pointing at a single static html page with no JS or cookies. If I'm doing anything in the browser (not necessarily opening new pages, just scrolling and such) I see more seemingly pointless activity in other files, including: 
urlclassifier3.sqlite cookies.sqlite cookies.sqlite-journal XPC.mfasl pluginreg.dat blocklist.xml cert8.db places.sqlite
(and probably others, that's just from repeated ls -lt | head in the firefox profile directory).
Most of these files are being updated even if you disable session store, even if cookies are blocked, etc.
