Linux

Ext4 bc of its speed for games and my main files. Btrfs on the root for compression

XFS on my server VMs and my laptops and desktops.

ZFS on my file server. I'd use it on my laptops and desktops too (and have done when I was using Xubuntu) but I've switched toFedora which doesn't come with a way to easily install with ZFS and I don't feel like jumping through hoops to get it done. And I can't stand btrfs. I don't know what it is about it, but I just don't like it.

Btrfs, ZFS and ext4. My servers use ZFS, my client machines mostly use btrfs and I have a sprinkling of ext4 partitions for specific workloads. I'm all in on CoW filesystems for snapshots, send receive, transparent compression and reflinks. I like btrfs on client machines and SBCs because it's easily available (baked into the kernel) and doesn't require maintaining dkms or holding kernel versions until ZFS supports them and because snapshot handling and other filesystem admin tasks are simple and straightforward. I run ZFS wherever data integrity is important, eg: storage servers and backup targets, but largely prefer working with btrfs.

It's all Ext4, but I run SnapRAID on top of that on my data drives. I'm sure lots of people would tell me I should use ZFS/BTRFS instead, but I'm used to SnapRAID, and I like the idea if something goes wrong, I won't lose all my data.

I use bcachefs for my games, I like that it lets me have multiple disks with redundant data copies, plus ssd caching of frequently accessed files, this fs is linux specific for now as far as I know, and is still experimental. I use ext4 for everything else, and FAT32 for flash drives.

Btrfs main boot drive

Xfs main storage drive

exFAT external "archive" drive (easy to connect to Windows machines if ever I need my backup in someone else's windows machine in an emergency and such)

Defaults

So Btrfs, ZFS and ext4 (ext4 is virtual only)

Whatever my installation CD had as default 😂. I'm guessing ext4?

I've been basically using btrfs on a lot of my disks because of the features it has.

Before I switched to a borg based system, my backups partition used btrfs for compression.

My main OS disk is btrfs so I can use timeshift snapshots, which are really worth checking out if you tinker with your system a lot.

I have two more btrfs partitions software raid0'd together for my steam library, nix store and other big but loosable things.

And my main home folder uses btrfs because I think the checksumming thing it does is more reliable for error detection, and cow is more fault tollerant on power failure?

... And I now fell like I'm one of those people with an over engineered storage solution. I just never get rid of old ssds or hard disks!

Pretty much all ext4 except for a few Windows installs on NTFS.

dual boot NixOS and FreeBSD on a single drive, ext4 on Nix and ZFS on FreeBSD. each partition has its own boot, swap and root, all encrypted

btw, OP wrote that FAT32 is limited, isn't it the default fs for the boot partition? can other fs like ext2/3 be used?

Btrfs for the compression and snapshots

We use btrfs for the / partition and xfs for any data partitions. Has served us well, the snapshot feature saves us some valuable time when an update goes awry.

Btrfs because it sounded cool when I first read about it and worked fine so far :3

NTFS Usally for windows,ext4 for linux,btrfs to install linux on,vfat/fat32 for cross platform compatibility

NTFS for the drive I had before jumping to Mint. Currently reporting several hundred gigabytes free, but refusing to make any new files, because... I don't know. I'll deal with it after an upcoming move.

The OS / home SSD is ext4, and so is the fat loud hard disk I recently purchased through an entire month of fighting Amazon over gift cards.

Most of my drives are EXT4, but I started using BTRFS a couple years ago and will be using it on all new installs from now on. I really like being able to make snapshots and compression reduces the install size quite a bit.

ext4, but the btrfs activity visible in the kernel changelog has slowed down recently after a long period of many bug fixes, so maybe I'll give it a try next time.

I use Btrfs for my root partition to be able to rollback if something goes wrong after update. XFS: in all other cases, since I hate the lost+found directory on ext4. Although I don't think there's any significant difference between ext4 and xfs in performance and reliability.

I tried exFAT for my USB stick but car sterio cannot read it.
