A ghetto hack would be to enable compression on the zvol (at least
zle) and then 0-fill available space. Granted it would still show as
"used", but it would decrease the amount of really used space.
But NVMe would still be better :)

I also recommend NVMe controller, it supports Deallocate(in SATA, it
is called TRIM.)
chuck has committed a lot of patches to NVMe controller in 13.0 Current.
Just install 12.1-STABLE, fetch pci_nvme.c from 13.0 Current, recompile bhyve.
It works great. stable/fast.

Try nvme, I believe that driver supports TRIM and I've had a lot
better performance with it over ahci-hd.

Hello.
I'm running zvol-backed Windows guests in bhyve on FreeBSD 12.1.
Over time, I see the zvol effectively used space grow in size: a sign
that Windows isn't trimming it.
I'm using virtio-blk: I guess this driver does not support trim?
I see reports that this support was added, but it's not
