From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What file systems are you using on your devices and why? (en.wikipedia.org)

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

I've only been put off with how slow it is in phoronix latest benchmarks

That's fair, it has changed a bit since then and I'm hoping we get another filesystem benchmark to see if it has improved, and the caching features might offset that on frequently used data, but I don't know how hard that would be to benchmark.

Oh, didnt know that was posted, some of the tests seem to be different from last time, it hasnt regressed but hasnt improved much yet either (from the ones that were the same). It does seem to have pulled ahead of BTRFS since the last test, doubling score in the DBench test, but it still varies a lot compared to the other filesystems it seems, doing worse pretty regularly.
