On: Ask HN: What Do You Use for Linux Full Disk Crypto?

(very soon) ZFS! It's happening: https://github.com/zfsonlinux/zfs/releases

The PR started 3 years ago: https://github.com/zfsonlinux/zfs/pull/4329

I've been using ZoL-git with Datto's encryption since 2017 on my main systems. It's really really solid and makes the management of encrypted datasets a breeze (even send and receive are supported). Yes, probably is slightly less sicure than LUKS/GELI and similar block-level encryptions, but I personally do not care that much. I can't wait to see it in stable ZoL and in FreeBSD (I'm also kinda hyped for ZoF, which I hope will allow to share easily pools between Linux and FreeBSD)

It's a shame it cripples the performance though. It roughly quartered sequential read/write for me.

Can you explain to me why i should use zfs instead of ext4?

You can compare ZFS to BTRFS, Ext4FS belongs to the late 90s. Comparing ZFS to Ext4 is like comparing a Pentium 100 Mhz to a Quad Core, asking why would someone want to use the quad core.
