Yep. Reply and Reply-All from Outlook 2016. Not sure who to blame for standards 
violation here...

smartctl. It has a vendor database concerning what each of the values are, so 
if the manufacturer of you drives says 233 = "Remaining Lifetime Percent", and 
the manufacturer of my drive says 233 = "Media Wearout Indicator", and the 
authors of smartmontools were aware of this, then that's what goes in the 
database and that's what gets reported.

Nah these particular ones were just in PC's, and were definitely not warn out 
(on the one occasion where I actually got one to read for a bit, the SMART 
values were all fine. Servers get SSD's with supercaps :)

Despite initial reservations (funny how you can easily find bad reports on any 
brand!) I have been impressed with the performance and longevity of the 
Samsungs, but I still don't have enough datapoints.
