so, i'm using lvm on linux, and the really cool thing about lvm is that in theory, i can move a live system from one SSD to another without even logging out. i tried this two or three times before and ended up manually restoring LVM metadata each time.
anyway,

You're reminding me of how excited I was to use f2fs on my shiny new Samsung 960 Pro 2TB NVMe SSD provided by a sponsor. I was happily benchmarking and testing my workloads on it compared to another SSD and realized it was giving me back any space after data was getting cleared.

I use xfs by default, including for backups, but I'm back to using f2fs for my main drive (this one). I was an early adopter of ext4 since it was the shiny new thing when I migrated over to using Linux as my main OS. The data corruption I had to deal with from that was less fun.

I mostly need performance and don't have a use case for fancy features. I'm either going to use a single f2fs partition covering the entire 2TB NVMe SSD or a single XFS partition. No need to ever resize it, combine it with other drives, apply compression, etc. Simple is fine.

But you've run into data corruption issues in the past; zfs will at least detect those - even if you're not using mirror/raidz - instead of returning bad data to your apps. xfs doesn't do that

By the way, I have 64G of non-ECC RAM... and that's going to become 128G or more when I upgrade this year from this 2016 workstation build. I would like to buy ECC RAM but I'm not buying a Xeon rather than an X series CPU so Intel doesn't think I should be allowed to use it.

only Pentium/i3 and Xeon support ECC. i5/i7/i9 do not
