I run everything through LVM after about the second time I crashed my root partition on plain ext2 by filling it entirely, at least probably 10-12 years now. LVM2 doesn't crash it like that even if filled, or cause a full fsck of fscking time and other weird catastrophic restoration of services.
If no encryption, you can set lvm2 to pass through ssd trim, or setup your own periodic trim jobs. I'd love to hear reasons not to use lvm, as it's dated, and looked at things like zfs and btrfs to replace 1) raid, 2) encryption. and 3) logical volumes, but without these all wasn't really an option. Curious if anyone's using any one native solution for all three yet. Using mdraid+luks+lvm+ext4 is still my general go-to.
