What file systems are you using on your devices and why?

I want to learn more about file systems from the practical point of view so I know what to expect, how to approach them and what experience positive or negative you had / have.

I found this wikipedia's comparison but I want your hands-on views.

For now my mental list is

  • NTFS - for some reason TVs on USB love these and also Windows + Linux can read and write this
  • Ext4 - solid fs with journaling but Linux specific
  • Btrfs - some modern fs with snapshot capability, Linux specific
  • xfs - servers really like these as they are performant, Linux specific
  • FAT32 - limited but recognizable everywhere
  • exFAT - like FAT32 but less recognizable and less limited

  • F2FS, because solid state and speed

    • Oh never heard of it. How's your environment suited for it then? Give some details please.

      • not sure what you want to know...

        1. have a solid state drive
        2. format it as f2fs

        done; just use it normally

        • Do you use it for USBs NVMe and SSDs or SSDs exclusive on the main system?

          • FAT32 for USBs, as I frequently need them to be bootable.

            F2FS for my M.2 NVMes, desktop and laptop, but would also use it on SATA SSDs as they're all flash.
