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

NTFS feels rock solid if you use only Windows and extremely janky if you dual-boot. Linux currently can't really fix NTFS volumes and thus won't mount them if they're inconsistent.

As it happens, they're inconsistent all the time. I've had an NTFS volume become dirty after booting into Windows and then shutting down. Not a problem for Windows but Linux wouldn't touch the volume until I'd booted into Windows at least once.

I finally decided to use a storage upgrade to move most drives to Btrfs save for the Windows system volume and a shared data partition that's now on ExFAT because it's good enough for it.

By default, windows does "Fast Boot" which doesn't make booting any faster, but does have the benefit of leaving the volume in a mounted state when you shut it down.

Oh, right. Fast Boot. I forgot about that bundle of joy.

But that's wasn't the only instance of an NTFS volume suddenly being broken. Another favorite was when I shrunk a volume on one disk from Linux (and then remembered that Windows correspond done it better) and rebooted to have it fixed and Windows proceeded to repair one on a different disk.
