Thinked some more. Journalling is just redirect of other apps, right? So I tried to disable journalling at all. And what do you think? Suddenly, another app was taking all I/O. It's "python onedrive-d start", glitchy sync app that I have been installed recently. Now my plot is:
1. Configure onedrive-d so it be not so intensive;
2. Re-enable journalling.
Solution is found, no glitchy commits is needed.

Title:
  jbd2 writing block every 5 - 10 seconds, preventing disk spin-down and
  making noise

Status in linux package in Ubuntu:
  Invalid

Bug description:
  jbd2 writes blocks to the hard disk every 5 seconds.  This makes an
  annoying click/tick noise and prevents the disk from spinning down to
  conserve power.  jbd2 appears in logs as several entries like...

   Jul 19 21:35:45 edge kernel: [ 3312.913759] jbd2/sda5-8(350): WRITE
  block 42280704 on sda5

  ... and can be observed using iotop. Since the noise only occurs in
  Ubuntu and not in Windows 7 it is probably a software problem.  The
  excessive writes may reduce the disk's lifespan.

  WORKAROUND: Adding commit=60 to the partition's entry in fstab
  increases the interval to 30-45 seconds.
