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.

Why not ZFS?

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

Yeah, they go out of the way to disable this in the hardware to differentiate Xeons. I love the X series CPUs for workstation usage. They're a specially binned Xeon die with a substantially higher base clock rate and unlocked multipliers (per-core multipliers, turbo ratios), etc.

However, they go out of the way to disable a bunch of the server features. Cost / value of X series CPUs is amazing compared to Xeons, especially if you pay $100 for a CPU cooler like noctua.at/en/nh-d15 and do a 30-40% overclock. I have an i7-6950X from 2016 @ 4.4GHz ATM.

X series CPUs tend to have fewer virtualization features available than even a regular i7, etc. because they disable as much as they can get away with to reduce the ability to use an X series CPU instead of a Xeon. It's ridiculous. I would pay more for an X series with ECC...
