I wonder if they enabled the same botched queued discard that they did
in 850 Pro?
If someone has an 840 Evo with the new firmware it would be helpful for
us to receive the output of:
# hdparm -I /dev/sdN
# smartctl -l gplog,0x13 /dev/sdN
I think I might have an 840 in the lab. Will head down and update it
later this week unless somebody beats me to providing the information
above.
