And how does one actually verify TRIM is working?  Most SSDs I've used
do not have a SMART attribute that can help determine this.  I would
rather not make a bunch of assumptions about Attributes 226, 232, or 233
to help give some indication of it working.

For folks to test this, there needs to be some indicator/verification
mechanism that it's working.
