tech question (btrfs) 

i'm reading about btrfs and still struggling to see any reason why i wouldn't just use ext4. there's gotta be a reason, right? i'm just not seeing any, especially if you just want a no-nonsense fs that you don't plan on interacting with all that much. snapshots and subvolumes and all that stuff just looks like a hassle rn

tech question (which filesystem for which use case) 

one thing that i can't seem to find is, like, a simple breakdown chart listing the dis/advantages of various fs schemas and which ones to use when

reading all this shit just makes my eyes gloss over and mentally check out and decide to stick with ext4 for no reason other than "it works and i don't wanna deal with this rn"

like: ssd vs hdd, read vs write, sequential vs random, if striping or mirroring are used, etc... which would be best/worst?

tech question (a filesystem for my specific use case) 

with all that said, here's what i'm lookin' at, if someone doesn't wanna help generally but they know some specifics:

- 4x 8TB HDD
- probably destined for a NAS use case (i'm thinking snapRAID with 1 of them for parity? i might add another 3x 4TB if so)
- probably going to store a lot of media (music/movies/tv on one volume, photography/video work on another, documents/graphics/etc work on a third? not sure but whatever)

tech question (a filesystem for my specific use case, 2/) 

the 2nd half of the equation is i'm probably gonna use a 500gb sata ssd as a system drive, and i'm kinda strongly leaning to just putting / on there

but i was also considering using the ssd purely for VM stuff and instead installing arch to a 32GB usb drive, unraid-style -- with my desktop environment(s) as a guest under kvm? i might possibly need to hash that out a bit more but that's a separate issue

@trwnh en.wikipedia.org/wiki/Comparis offers several features lists for A LOT of fs.

But it's a flood of features not especially important and no conclusion (that would potentially violate NPOV). So more useful to answer questions like "what fs has ..." or "is ... has ...".

If speed is important, check phoronix.com/scan.php?page=art and phoronix.com/scan.php?page=art

You'll notice ext4 has good write performance. So if you write a lot, it's not bad to use it.
