Client doing an insane amount of writing to disk

[Formina_Sage]

I'm wondering if anyone else can second this finding. I was reading a thread about Spotify killing SSDs due to writing large amounts to the disk on a constant basis (https://community.spotify.com/t5/Desktop.../1365378). Curious, I opened Task Manager and found that the largest writer is not Spotify, but Whatpulse. You can check this yourself on Windows if you open Task Manager, go to the Processes tab, then add the "I/O Write Bytes" column in View > Select Columns...

Check out Whatpulse's usage. On my PC, it's the highest at having written 44GB to disk since the computer was last rebooted (4 days ago, and the computer was sleeping most of the weekend). Even at times when the computer is idle. Whatpulse.exe is constantly writing to disk. This is, as the spotify article mentioned, bad for SSDs that die faster with constant use. I imagine it could also be indicative of a performance hit, since the process is constantly using the disk.

My question for the devs is, what is the application constantly writing? Even if it's updating the database on disk after each keystroke/click/whatever, how could that amount of data possibly add up to 44GB?
