Samsung 980 Pro Gen4 2TB NVMe M.2 SSD Review – The Bigger They Get


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.



Crystal DiskMark shows that throughput is very close to the money although we aren’t seeing anything close to the 1 mil IOPS as per spec.  Many might not notice but the low 4K random read of 83.3MB/s is very high in comparison to the norm and something very good to see.  This just might result in a slightly faster system operation.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.




Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.


The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.


TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features.  Advanced load bench-marking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.  Simply click on the title for a free copy.


  1. Summer 2019 I installed two Samsung 250gb 970EVO Plus m2 sticks in my msi 390 z mpg board. Put them in raid0 to be used as the c drive. I7 8 core CPU. PC boots to win10 desktop in 5 seconds after the POST beep!

  2. “and memory has been set at a XMP profile of 2667MHz”
    What? The linked RAM kit listed should be XMP speed of 3600, not 2667.

    • Yes… you would be correct but we can see that that is not the memory in the system posted. We switch off so much for different testing that was inevitable at some point. Our mistake and will correct. Nice observation. It’s great to have readers that notice such.

  3. Samsung still hasn’t released their driver for 980, so I assume that’s why at this moment this drive makes no sense (alternatives from Seagate and HP give even better results for cheaper price).

  4. ….telling my age also, but you can still find gum sticks at convenience stores and (in NYC) Bodegas. Just sometimes have to look for them 🙂
    Hope to get a 2TB stick when available for me to get. When installing it, I will reflect back to the time I bought my first 40gig HD and felt that I would never need another drive except for migrating my old system to another drive. Now I’m “really telling my age”.

    • Yes I am right there with ya.

      • My computer with Z490 ACE with i7 10700k and 2TB m.2 970 EVO Plus boots in one second or less skiping post screen all together. You hit the boot button and it fully boots before your finger can leaves the button. CPU rarely hits 70 degrees even when overclocked and most the time it runs overclocked at 60 degrees. Upscaling 1080p to 4k and it looks great and I still get 90 to 120 FPS. Upscaling the game’s looks great for some games and takes up less GPU memory in my build. I’m using a 2080 super and loving it. I think I’ll wait for 5080TI to upgrade very likely unless others became super cheap. I’m going to wait for 980 Evo Plus to upgrade my m.2 drive. When buy a Z590 ACE and give my old set to my younger brother I’ll be upgrading RAM also my then when they will have the super fast RAM developed even if it would likely take a Z690 ACE upgrade to full benefit from it. Maybe persistent memory will be cheaper at that point so I can use two RAM spots for normal RAM and two for persistent memory. I don’t have a high HZ 4k screen to test native 4k next to 1080p upscaling but it looks very good on Alienware 27inch 1080p monitor.

        I asking myself if it would look all that much better other then the clearly much greater color range on the new 1480p monitor or would upscaling 1480p to 4k just lower FPS maximum below my current 90 to 120 FPS range? Does native 4k actually just lower FPS so much over upscaling and take more GPU memory?


    My 1986 PC Clone had a 30MB HD. It helped me launch my freelancing career as a software developer after leaving my IT job at the bank I worked for.

  6. Overall the 980 Pro is a great drive, it’s one of the best drives available on the market today, and while Samsung has done a good job improving performance for light and medium workloads, there are some situations where the 970 Pro is faster than the new 980 Pro. In the PCMark 8 benchmark, the 980 Pro scores around 670 MB/s in both capacities, but the old 970 Pro is scoring 840 MB/s in that benchmark even though it doesn’t have PCIe 4.0. I think this is because of the shift from TLC to MLC memory. At the end of the day, you get what you pay for, techniques like DRAM and SLC caching can cover most of the deficit of TLC memory, but not all of it.

    • Agree with you totally. As nice as TLC may be, there is a point where it simply cannot keep pace in data transfer or steady state transfer of very large packets of data. A bit amusing perhaps, when you look at pricing for older drives, one will see that they actually jump significantly in price as they use mlc, or even earlier TLC.
