ymcapc :
By using Rapid Mode on Samsung 850 Evo 120GB will it extend the life of the SSD?
It will neither extend nor shorten the life of the drive.
It uses some RAM as a cache.
It also does not, in normal use, show any actual benefit.
I had it running for a while, with 2 different Samsung drives. 840 EVO 250GB and 850 EVO 500GB.
On...Off...I saw zero actual difference in daily use.
