What file systems are you using on your devices and why?
What file systems are you using on your devices and why?
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

ZFS where possible for maximum reliability
It also has self healing, no "partitions", high performance, compression, smart drive redundancy without RAID holes, encryption, deduplication and an extremery intelligent cache called ARC
ZFS is completely ridiculous. It's like someone actually sat down to design an intelligent filesystem instead of making a slightly improved version of what's already out there.
Holy xfs is probably not close to that?
XFS is simply a journalling filesystem.
ZFS is a COW filesystem and volume manager with compression, block management, and an adaptive read cache.
Kind of an apples-to-oranges comparison.
Technically XFS is also a CoW filesystem, but it doesn't have the vast array of features that ZFS does like volume management, snapshots, send/recv etc. It does have reflink support which I guess is a kind of snapshot for a file.
Well, encryption is very much not a strong point of zfs. I agree on all other points tho.
Actually native encryption has been a feature of ZFS for a few years now. It's nice not having to have an extra LUKS layer.
