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 filesystem is currently best for a single nvme drive with regard to performance read/write as well as stability/no file loss? ext4 seems very old, btrfs is used by RHEL, ZFS seems to be quite good... what do people tend to use nowadays? What is an arch users go-to filesystem?

ext4 being old, and still being the main file system most distros use by default, should be enough alone to tell you being old isnt bad.

it means its battle tested, robust, stable, and safe. Otherwise it wouldnt be old and still be in widespread use.

This is exactly my outlook. Ext4 has proven itself as a robust and reliable file system.

RHEL uses XFS as default.

i would generally recommend XFS over ext4 for anything where a CoW filesystem isn't needed. in my experience, it performs better than ext4 at most workloads, and still supports some nifty features like reflink copies if you want them.

Currently running BTRFS. Next fs is gonna be ext4. No need for anything else

Are you saying you don't like btrfs?

It makes recovery harder, and it's just not something I need
