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.

I like BTRFS's checksumming abilities and compression the most. BTRFS will keep track of every block of data's checksum, and when you run a
scrubit will detect bitrot. If you want to heal the bitrot you'll need to run e.g. RAID1. RAID5/6 are not stable so don't use those. ZSTD:1 compression is basically free storage with no downside, and can massively speed up file operations if you're using spinning rust.Personally I run BTRFS on any disk that only needs a single drive, like OS disk or games drive. My NAS runs a ZFS array for any mass storage, which includes basically the same feature set as BTRFS, except RAID actually works and everything is a tiny bit better. A ZFS NAS isn't very good unless you pump a decent amount of money into it to get it going, so if you're on a tight budget I'd recommend MergerFS+SnapRAID backed by BTRFS disks, which is very similar to Unraid in terms of storage paradigm except free.
