Introduction, Specifications and Packaging
We have been overdue for a Samsung NVMe SSD refresh, and with the launch of their 860 PRO and EVO back in January, folks have been itching for the 970's to come out. The 950 and 960 (PRO) lines were separated by about a year, but we are going on 18 months since the most recent 960 EVO launch. Samsung could afford to wait a bit longer since the 960 line already offered outstanding performance that remained unmatched at the top of our performance charts for a very long time. Recently, drives like the WD Black have started catching up, so it is naturally time for Samsung to keep the competition on their toes:
Today we will look at most of the Samsung 970 PRO and EVO lineup. We have a bit of a capacity spread for the EVO, and a single PRO. Samples are hard to come by so far since Samsung opted to launch both lines at the same time, but we tried to get the more common capacities represented. EVO 2TB and PRO 1TB data will have to come at a later date.
Specs come in at just slightly higher than the 960 lines, with some welcome additions like OPAL and encrypted drive (IEEE1667) support, the latter being suggested but never making it into the 960 products. Another welcome addition is that the 970 EVO now carries a 5-year warranty (up from 3).
The 970 EVO includes 'Intelligent TurboWrite', which was introduced with the 960 line. This setup maintains a static SLC area and an additional 'Intelligent' cache that exists if sufficient free space is available in the TLC area.
Packaging is in line with the previous 960 series parts. Nice packaging. If it ain't broke, don't fix it.
Introduction, Specifications and Packaging
This is it. This is the day we have been waiting for. Ever since we feasted our eyes on the NVMe version of the Samsung SM951, we’ve been begging Samsung to release this as a consumer product. Bonus points if it was powered by their 3D VNAND technology. It took them a while, but they came through, officially announcing the 950 PRO exactly one month ago, and launching them today! Not only will we dive into the performance of this new model, we will also include its results in our new Latency Distribution and Percentile testing.
Nothing has changed since the announcement. All specs remain the same very impressive 2.2-2.5 GB/s reads, 0.9-1.5 GB/s writes, and upwards of 300k IOPS, all from an M.2 2280 SSD consuming only 7 Watts!
While the 950 PROs will work with the built-in Microsoft NVMe driver (present in Windows 8 and up), Samsung has also provided their own driver, which will increase performance. The same was true for the Intel SSD 750 Series.
There’s really not much to this packaging, but it’s the most ‘retail’ we’ve seen for packaging of a simple M.2 SSD.

Once a technology is released to the public, the only thing stopping you from knowing how it works is the ability to look inside. With detailed imagery of 32-layer VNAND recently released by TechInsights, not only was Andy able to conduct a very thorough analysis at his blog, we are able to get some incredibly detailed looks at just what makes this new flash memory tick:
Flash packaging, showing interconnect traces (which connect the outside of the package to the flash dies contained within).
1x: The 3D VNAND die itself. We'll use this as a point of reference of the magnification levels moving forward.
350x: This is the edge of the die, showing how the word (data) lines are connected to the individual layers.
1,500x: There it is, all 32 layers in all of their vertical glory. The only thing more amazing about the technology at play to create such a complex 3D structure at such a small scale, is the technology used to slice it in half (some of the material is tungsten) and take such a detailed 'picture' of that cross section.
30,000x: Finally, we have a top down slice of the channels themselves. This lets us get a good idea of the rough process node at play here. While the columns are 80nm in diameter, there are other features that are smaller, so the process itself still seemes to be in the ~40nm range.
Our focus is of course on the performance more than the extremeny low level bits, but it is definitely cool to see imagery of this new tech. For those curious, we encourage you to check out the detailed analysis done over at 3DInCities.
