Hello Mark,
Yes, I think that it's related to the WD Green SSD.
Today I found this bug on FreeBSD's bugzilla:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225666
Tried to reinstall and recompile the kernel with the patch but it didn't
work, I continue to see corrupted data.
I think that the only way to be really sure about the corrupted data is to
reinstall again but already boot with the quirks configured, but the
kern.cam.ada.X.quirks don't seems to exists on FreeBSD 12,
so I have a probability of corruption between installation and compilation
of the patched kernel...
Don't know what more to do...

Hi, please forgive my lack of experience with ZFS, but with regard to
buggy SATA something hasn't been brought up yet:
If ZFS is sitting on top of GPT, what sectorsize and offset are used?
What blocksize is "native" to the drive? Are these aligned?
I recall this chance for misalignment being a cause of silent write
corruption after installing a new SSD for Apple MacOS; maybe FreeBSD ZFS
on SATA happens to be similarly susceptible.
