Samsung SSDs - Am at the end of life?

[Mark Phillips]

Matthew,

I am still confused. If the wear leveling count counts back from 100, one
drive has a raw value of 3 and the other one has a raw value of 22.

ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED
WHEN_FAILED RAW_VALUE
177 Wear_Leveling_Count     0x0013   098   098   000    Pre-fail
Always       -       22
177 Wear_Leveling_Count     0x0013   098   098   000    Pre-fail
Always       -       22

However, the VALUE column has a value of 98. Not sure of the units for
either column...
