I built my home system early this year using the Samsung 960 Evo 1TB M2. Actual speeds were nowhere near advertised speeds until I enabled write-back cache on the drive, which gave me pause for concern about data persistence reliability. AFAIK the Samsung drivers (as opposed to the MS drivers I originally used) just turn this on without needing to be twiddled in settings.
Just to confirm, I have seen the behaviour described herein, with write-back cached making enormous difference with the Samsung EVO product in particular.
