I planned on upgrading to a Samsung 960 Evo 250gb for a main/OS drive. Its $~60-70 more than a Western digital blue 3D nand m.2. There's a significant increase in speed (540/530 read/write vs 3200/2400 read/write roughly) but the WD blue has a much higher tbw (100tbw vs 500tbw) and seems more reliable. My question is would I benefit from having the 2x faster Samsung or should I just save my money and stick with a more reliable cheaper WD blue?
