Sounds likely?  No errors on non-SSD either

wd2 at atabus3 drive 0
wd2: <WDC WD80EFAX-68LHPN0>

Since I've set hw.wd0.use_ncq and hw.wd1.use_ncq to 0, I've not had a
repeat of the problem.

However, I've had some corruption :(.  fsck has fixed a number of
errors and I also have (so far) a couple of dozen corrupt files.

Cheers,
Simon.
