@roboneko @sjw @djsumdog @mononoaware @ExtraSpecialK @okabe_rintarou Linux distro usually goes with ext4 by default I believe

In general, ext has been the de-facto standard filesystem for over two decades. ext3 added journaling (a means to prevent filesystem metadata corruption in the case of a power outage during a write) in the very early 2000s and I can't remember what ext4 added. Ext4 is tried, tested and standard.
Reiserfs was interesting, but the lead developer murdered his wife, so no one talks about it any more :blobcatsweat:
ZFS is a file system used a lot in the BSD world, originally developed by Sun. With ext4, if you want RAID you put your ext4 on top of mdadm (Linux software RAID). If you want encryption, you put ext4 on top of LUKS. If you want logical volumes, you put ext4 on top of a Logical Volume Manager (LVM). ZFS is the other direction. You can have ZFS handle many RAID types natively, encryption, data pools/volumes, snapshots and many other features like de-duplication. You don't need to layer it on top of something else (you still can, FreeBSD doesn't use ZFS-native encryption and instead puts ZFS on GELI).
Unfortunately, ZFS can never be part of the mainline Linux kernel due to licensing. It's not GPL compatible. Btrfs is an attempt to make a more powerful filesystem for Linux, that supports snapshots, RAID, etc. Unfortunately, anything beyond RAID0/1 for btrfs is terribly broken. It's a stable filesystem, but doesn't do a lot of advanced file system stuff yet (it does support snapshooting which is really cool).
If you're just starting out, none of this matters and stick with ext4. When you feel ready to play with stuff, look at ZFS for your storage/data drives. Snapshotting is really good for creating and moving around incremental backups.

I've heard that thing about never spinning down your drives to make them last longer (as if the on/off cycles cause wear), but that sounds like weird superstitions BS. After all, you can also set them to spin down when not in use to save energy.
Modern hard drives are pretty reliable. Big thing: always keep backups. Once a month or week. Nothing beats a backup.

@djsumdog @roboneko @sjw @mononoaware @ExtraSpecialK @coolboymew I know about ZFS from a prior recommendation of TrueNAS in a thread I created about data storage (where you might've also posted). A home NAS is something I'm considering a year now, but like with Linux, I had many worries about it.
You seem to know something about running RAID and possibly NAS systems, so since I have your attention: Do you know if it matters much for a home user like me if I shut down the NAS system daily?
I have an older PC with an Intel CPU (around 12 years old) where I wanted to just put in lots of Western Digital Blue hard drives and run them in RAID 1 via TrueNAS. My plan was to just occasionally run it, whenever I'm at my PC, but some people are absolutely against ever turning a NAS system off and therefore the hard drives of it.

But that's what I intended RAID 1 to do. :blobcatbolb:
