Running on battery power with reduced bus speeds and low power states reduces performance by ~25%. If the Samsung SSDs ran the same way we would see a score at (or close to) 2000. The drive delivers the highest workload performance, but also the worst battery time. Patriot did us a real favor when it released the Hellfire without any power optimization for notebook battery use. The two new Samsung NVMe SSDs deliver higher performance on battery than the 950 Pro. Power optimizations are one of the last areas addressed in firmware development, so it's possible that Samsung could nudge a little more power performance from both of the new NVMe products. The SM961 and PM961 are right together, but we don't want to put too much emphasis on this test now. TLC uses more power than MLC because of the eight power states that it uses to identify the three bits stored in each cell. Samsung takes the top three spots again, but this time we find it leading the notebook battery life charts.

The company released the statement and even put it on the retail box "don't use this product in RAID mode with Intel's onboard RAID." We will revisit the issue when Samsung releases the retail products with the Polaris controller. OCZ was the first company to reveal that some NVMe SSDs have issues with the Intel PCH RAID. Some users have reported more stability with other motherboards.

The Z170 board would only operate for a few seconds to a minute before entering a fault state and restarting. The Polaris controller didn't play well with our Asrock Z170 motherboard in RAID when we tested the Samsung SM961 1TB. The PM961 is very consistent, and that helps in consumer RAID 0 arrays. With some of the other products, the performance ebbs and flows (which is what you don't want). Normally we wouldn't consider a mainstream product for RAID use, but the PM961 delivers solid, consistent performance. TLC cuts the steady-state random write performance in half compared to Samsung's MLC SSDs.
