Ask HN: Linux Ext4 Disk Optimization

If ext4 need no defragmentation then how/what definitively to optimize its disk access operation

Nothing ext4 specific IIRC. There are some kernel optimization you can do, like this, but consider some of that to be a placebo:

Other than that, maybe consider an alternative filesystem like f2fs or xfs depending on the medium.
