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

Ext4 for everything when possible, because its reliable and proven. I'm looking towards Btrfs for my next system drive, as it is mature now and has good features. But I would use Ext4 for everything else still. For interoperability that doesn't understand Ext4 it would be NTFS when supported, otherwise fallback to FAT32.

That's the entirety of my knowledge and what I use when I have to format it myself. :D

I respect your reliable and proven comment. I really love the features of BTRFS and that’s why I use it, but I also really care about my data. I have secondary installations that use EXT4 and work very well.
