249 is the number of gigabytes written to NAND.
No references found, I just guessed it from another DB entry with the
same number and
the value's dynamic when testing a brand-new drive (it went from 0 to 3,
then to 5 when I performed yet another write test that writes ~1GiB of
data).
Last but not the least, drivedb.h parser in Smartctl 6.5 turns out to
ignore the lines
that have the // comment, even if it's not the first token in the line.
That's why there are so many unknown attributes in the output.
I reported it at https://www.smartmontools.org/ticket/854 .
