ZFS writing to disk frequently - every 5 seconds

I have two ZFS pools on my server.  One is a ZFS mirror where all my app data(dockers/VM's) is stored and I have another ZFS2 for data.  The ZFS mirror is constantly writing data every 5 seconds and my understanding this is normal for ZFS.  My question is there some tuning or something else like a SLOG I could set up that would improve the constant writing to disk without impacting data integrity?  Currently, my server sits in the living room and it's quite noisy when the disk is written to every 5 seconds.  

 

Some ideas

* install a SLOG SSD 

* adjust sync from standard to none

* adjust zfs_txg_timeout
