alright i have a ✨Diabolical Plan ✨
instead of just installing arch normally, i'm gonna boot into the install iso, format the empty partition i created from win10 as ext4, use fbcat(1) or something to make a screenshot, save it to that partition, and then try to mount that from WSL to post the screenshot on tumblr.
I giggled to hard.
File System Implementations Linux supports many different file systems, each designed with different goals such as performance, reliability, scalability, compatibility, or storage efficiency.
nobody talks about file systems until their data disappears
okay so i've been getting asks about linux file systems and honestly? this is one of those things where the choice actually matters but nobody tells you WHY it matters.
so here's the thing.
the setup
when you install linux, you pick a file system. most people just hit enter on whatever the installer suggests. and look, that's fine! but you're choosing between three very different philosophies:
ext4 - the responsible adult
Btrfs - the chaotic good wizard
XFS - the speed runner
let me explain.
ext4: the one everyone knows
ext4 is like that friend who always shows up on time and never cancels plans. been around since 2008. ubuntu uses it. debian uses it. it just works.
pros:
stable as hell
fast enough for everything
if something breaks, there's a fix
your grandma's linux install probably uses this
cons:
no snapshots (yes this matters, we'll get there)
no compression
honestly kind of boring but in a good way??
use this if: you want your computer to work and don't want to think about file systems ever again
Btrfs: when you want superpowers
pronounced "butter FS" and yes i'm serious.
okay so imagine you're about to do a system update. with ext4, you just... hope it works. with Btrfs? you take a snapshot. update breaks something? rollback. it's literally that easy.
also:
compresses files automatically (hello extra disk space)
checksums everything so you know if data gets corrupted
can literally take snapshots while the system is running
fedora ships with this now
but here's the catch: it's more complex. uses more RAM. some features are still experimental. RAID 5/6 is broken and has been for years (don't use it).
the vibe: you're comfortable with linux and you want modern features. maybe you're running a home server or NAS. maybe you just like being able to undo mistakes.
use this if: you value flexibility over simplicity and you're not afraid to learn some new commands
XFS: for when you need SPEED
this is the file system that doesn't mess around.
made in the 90s for supercomputers. now it's what Red Hat uses by default. recent benchmarks show it's about 20% faster than the competition for high-throughput stuff.
great for:
massive files (we're talking terabytes)
video editing
databases that need to go FAST
anything where you're moving huge amounts of data
limitations:
can't shrink it (only grow)
no snapshots
kind of overkill for a regular desktop
use this if: you handle large files regularly or you're running servers and performance actually matters
the part where i get philosophical
here's what's cool about linux: you can use different file systems for different things.
root partition on ext4 for stability? sure.
home directory on Btrfs for snapshots? absolutely.
external drive with XFS for your video archive? why not.
the "best" file system doesn't exist. it depends on what you're doing.
my actual recommendations
just want linux to work: ext4, no question
home user who wants snapshots: Btrfs (fedora already did this for you if you're on fedora)
work with big files/video/databases: XFS
setting up a NAS: probably Btrfs for the snapshot capability
enterprise server: XFS if you're on RHEL, ext4 if you want maximum stability
the technical rabbit hole
if you want the full deep dive—benchmarks, optimization guides, migration strategies, all the nerdy details—i wrote a comprehensive guide with actual data from 2026 kernel testing.
it's got:
performance comparisons
feature breakdown table
specific use cases
optimization tips for each file system
answers to "can i convert between them" (spoiler: backup first)

https://linuxano.com/linux-file-systems-explained-ext4-vs-btrfs-vs-xfs/
final thoughts
honestly? unless you're doing something specific, ext4 is fine. it's been fine for 15+ years. it'll be fine for 15 more.
but if you're curious about what's possible—snapshots that save you from bad updates, compression that gives you free disk space, or just maximum speed—the other options are there.
and that's what i love about linux. the choice is yours.
what are you running? drop it in the notes. i'm genuinely curious about what file systems people actually use in the wild.
reblog if you learned something / have strong opinions about file systems / just like yelling about linux

#Journal no es necesario - Despejando #mitos sobre la #recuperación y el #arranque rápido en los sistemas de archivos #ext3 #ext4 #reiserfs #reiser4 #xfs para optimizar
Un sistema de archivos con journal realiza un seguimiento de los cambios aún no comprometidos con el sistema de archivos utilizando un registro circular. Se usa solo para recuperarse después de un desastre lo más rápido posible. No se trata de datos seguros o de copia de seguridad de datos de nuevo corrupción.. concepto erróneo común de los usuarios de Linux. Por lo tanto, cualquier…
