A fairly good chance, since WD licensed the entire design, including the
firmware, to lots of companies. How much Davong changed it could range
from 0 to 100%, but I doubt that they really had any motivation to do
much to it. All they really needed to do was to make a PC host adapter
for it, which was trivial, so it seems unlikely that they would have wanted
to spend a lot of time hacking 8X300 code.

The -05 suffix parts were entirely different than the original models.

Both the WD1000 and the WD1001 were originally designed to use the 8X300,
although the 8X305 was sometimes substituted.
