It would be, if it was correct. Megacli displays:
Sector Size: 512
Logical Sector Size: 512
Physical Sector Size: 4096
But lsblk displays 512 for everything. The disk says it uses a 512e format
with the 'e' meaning it emulates 512 even if not 512.

I'm also seeing the linkspeed, NCQ setting, drive temperature and
Manufacturers serial number -- all things I would expect out of the
kernel. I thought I remembered seeing temps displayed in linux as
well. Hmmmm.
Thanks for the pointer & response!
