None of these manufacturers rates these drives for massive amounts of
writes.  They're sold as suitable for laptop/desktop use, which
normally is not a heavy wear and tear operation like a DB.  Once they
claim suitability for this purpose, be sure that I and a lot of others
will dive into it to see how well it really works.  Until then, it
will just be an expensive brick-making experiment, I'm sure.
