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

ext4 because its the default and works fine

Never doubted it. Do you use journaling feature on it?

Every year I buy a couple ~$5 USB drives and plug them into my jbod machine in a software raid1. At this point there’s about a hundred in long array of daisy chained USB hubs.

Each drive is formatted with fat32 and added to an LVM. Don’t judge my ghetto NAS.

how fast is it?

I wouldn’t be suprised if that’s the case for Windows users.

ExFAT is the LCD filesystem for flash sticks. FAT32 is the filesystem that you have to use for devices designed before Microsoft was awful about Exfat licensing.

Everywhere else, Btrfs. If Oracle didn’t poison-pill ZFS licensing and it was common on Linux, I would be using that instead. Basically, taking it on faith that a drive didn’t fuck up your data is crazy. The most basic responsibility for a filesystem should be ensuring that “the files come out exactly the same as when they went in”.

ZFS on anything storage related. Enterprise level snapshot and replica management.

How’s it better than XFS? I heard same things about it too.

  • Btrfs on my laptop with openSUSE, mainly because it’s default, but also for its snapshot capabilities.
  • Whatever file system my default Raspberry Pi installation uses (probably Ext4).
  • NTFS on my main computer With Windows 10, because… well… I don’t really have any other choice, although I know there’s some kind of 3rd party Btrfs driver for Windows as well and you can ever have boot partition formatted as Btrfs, but I think it’s still experimental.

Btrfs snapshots have saved my ass a few times with bad updates.

ZFS all the things. On my workstations, I wipe / on every boot except for the files that I specify, and I backup /home to my NAS on ZFS and I backup my NAS snapshots to Backblaze.

Not only is there btrfs support for Windows, but since windows and linux root structures don’t conflict, someone got both arch and windows booting from the same partition. Is it a good idea? Hell no. But can it be done? Apparently yes.
