File system type and mount options for Archlinux on NVMe SSD drive

I know that there are many articles and wiki available for this matter, and I have read many of them already. But I'm still confused also because some of them are probably outdated. So maybe I can clarify some doubts here...

I want to install Archlinux (which is a rolling distro, so latest kernel, latest drivers, latest everything) on my new Dell XPS 13 laptop equipped with a NVMe CX2-8B512-Q11 NV SSD drive alongside Windows 10. I've already shrunk windows partition, disabled fastboot and secure boot etc.

The question is now about which file system to choose for /. I've read some articles and I learned that:

  • BTRFS is cool but still unstable. I read of people being screwed up using it. So it's not recommended at this stage.

  • EXT4 is the most reliable one today and the only down side is jounaling with takes space on the drive.

  • F2FS is designed for SSD but still tricky at this time to get it running.

So the best choice for a stable system as of today is EXT4, right?

About mount options: DISCARD seems to be deprecated an not recommend. Arch wiki advise to enable periodic trim service. Are there other mount options to add to fstab (e.g rw,relatime,data=ordered)?


I have two NVMe drives in my Lenovo P50 running Arch, no issues so far, running ext4.

I have fstrim.timer enabled instead of using the discard option in fstab.

sudo systemctl enable fstrim.timer

The only other notable option is:


You'll want to get rid of:

  1. relatime
  2. diratime
