Samsung 850 EVO and Pro 2TB SSD Review – 2TB SSDs Make their Entry


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 SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:

  • Windows Defender In Use
  • Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
  • Importing digital photos into Windows Photo Gallery
  • Starting the Vista Operating System
  • Home Video editing with Movie Maker which can be very time consuming
  • Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as Xbox
  • Cataloging a music library
  • Starting applications


The Samsung 850 Pro 2TB SSD provided excellent transfer speeds in all eight tests, seven of eight resulting in strong SATA 3 speeds.  The Total Score of 81464 is on course, and even a bit above, with what we would expect in today’s SATA 3 SSDs.

    To be frank, V-NAND was not needed for 2tb ssd.
    Manufactureres can easily stuff 16 packages each having 128GB space using plain ol’ 2d nand.

      Yes but…the problem then becomes one of performance versus the ability to provide the necessary power to the chips don’t you think? And how about DEVSlp?

        If sandisk managed to make 4TB ssd with ordinary 2d flash, i’m sure sammy could aswell.
        But in just happens that there was no demand, when 19nm was still a thing with samsung.

        And i dont think 3d is all that more power efficient compared to 2d to be an excuse…

        What about devsleep ? Care to elaborate ?

        To compare apples to apples, the SanDisk 4TB was originally shipped as a 15mm ‘z’-height form factor, as opposed to 7mm ‘z’-height for the Sammies. I do believe that SanDisk now fits 4TB into a 9mm ‘z’-height form factor. Those “taller” ‘z’-heights won’t be fitting into too many laptops or other portable devices.

        The 4 TB SSD was a dual PCB design and could never fit into a notyebook case. Further, it was noit a consumer SSD. I don’t think with the powering needs of an SSD with so many chips can DEVSLP be an option; I could be wrong.

        Well, with 3D there are still the same amout of chips or dies compared to 2D.

        Remember, 3D NAND has the same die size as 2D — 128Gbit.
        So for 2TB, they need the same number of dies, be that 3d nand or 19nm 2D.

        And fitting physically so much space was never a problem of chip density. We can do 256GB per package for quite some time now (840evo msata anyone ?).
        If we put aside controller and heat limitations, we could put 4TB of flash on a standard 2.5″ formfactor , if there was demand for such drive.

        Actually, according to a comment by Paul Alcorn from Tweaktown, the SanDisk 4 TB SSD has 3 PCBs:

    nice review les, Might these drives push the 1/2 tb models finaly closer to the $200 price point? Im still running on my Mushkin Cronos Deluxe 120 … but I think its getting long in the tooth & while I think a move to a 256 gig SSD would probly be financialy better for me … I notice the 1/2 tb’s are getting around the $300 mark. Also my other issue is im again if you remember running a AM3+ FX cpu, so im not 100% committed to replacing the board with Zen just over a year away. Sugestions?/thought?

      I don’t really think so. As much as we enjoy seeing the lower per GB point, these drives do not compete as they are still niche and in their own space IMO.

        I do not understand how ordinary consumers feel content with new computers coming off the shelf as sluggish as it were 5 years old. In actuality I HAVE put them in 5 year old machines and it’s much much faster than those new budget machines.

    Not to hijack the discussion – but any M.2 SATA 850 Pro or EVO with higher capacity, or are we stuck forever at 500GB? The technology appears to me similar, yet Samsung M.2 reached 500GB some time ago and stopped.

    No newer FW-version than the one which bricked a lot of users’ 850 Pros (luckily my update went well) huh?

    “Samsung has set a new bar in SSD pricing”

    Are you kidding? The best bar that the Samsung 2 TB SSDs set is $0.40/GB. The competition’s 960 GB/1 TB SSDs regularly hit $350-$380, the Crucial M500 960 GB was $295-$305 until recently. This is the 840 Series all over again, where reviewers gave Samsung and their 840 Series TLC SSDs all the credit for the SSD price drops that the Crucial M500 series started.

    so…. where can i buy 1 of these Beast_

    Why are the PCB photos of EVO rotated the other way of the PRO? It makes it difficult to compare the chips of EVO and PRO, or was that the point?

  8. blank

    Can I partition this SSD as a logical drive? I have a 500GB 850 EVO
