Corsair MP600 Pro XT Gen4 NVMe SSD Review – Yet Another Shining Example of Phison E18 Success


PCMark 10 Storage Benchmarks produce an overall score as a measure of drive performance. Comparing devices is as simple as comparing scores. The tests also measure and report the bandwidth and average access time performance for the drive. Each test uses traces recorded while performing real-world tasks such as booting Windows 10, starting applications such as Adobe Photoshop and Illustrator, working with applications such as Microsoft Excel and PowerPoint, and copying several large files and many small files.

In doing a comparison of other drives that we have tested on this Intel Test Bench, we can see that the Corsair MP600 Pro XT Gen4 NVMe SSD placed right in behind the  Seagate FireCuda 530 and ahead of its brethren Phison sample E18/B47R SSD.



The Quick System Drive Benchmark is a subset of the Full test and is more representative of typical daily usage to show what would be expected regarding hybrid SSD performance on a day-to-day basis.


Surprisingly… only because this is the reverse of the Full Benchmark result, the Corsair MP600 Pro XT bettered the Seagate Firecuda 530 and sits right beside our sample Phison E18/B47R SSD.



For our True Data Testing, we simply loaded 15GB video, music, photo and OS files onto the Plextor M10P Gen 4 NVMe SSD and copied the data to a new folder on that same disk.


Here we go.  Our True Data Testing demonstrated something rather special in the Corsair MP600 Pro XT.  Traditionally, the Achilles Heal of date transfer lies in those very small and numerous OS files.  As an example, our OS data sample contains 24,233 files where our video sample has only 24 files.  The Corsair MP600 Pro XT Gen4 NVMe SSD is the second best result we have ever received in testing OS data, just behind that of the Plextor M10P.


In this report, we have established something we already knew. The Phison E18 Gen4 NVMe controller is one of the best out there and Corsair made a very wise decision listening to the advise of Phison in creating this Phison E18/Micron B474 combination.  The MP600 Pro XT is one of the top SSDs on the market with data throughput above 7GB/s and IOPS well above 1 million.   For those that need the space, it will be available in 4TB (be it at a very premium price point). in addition to 1TB and the 2TB version we are testing today and it comes with a 5-year standard industry warranty.


It wasn’t so long ago that we spoke so highly in our report of the Seagate FireCuda 530 and performance in the two SSDs runs neck in neck…except for one thing.  The Corsair MP600 Pro XT cuts through small OS files like butter, and we have only ever seen that with the Plextor M10P.  Both the MP600 Pro XT and the FireCuda 530 have 5-year warranties but Corsair adds to their product by including a rather amazing looking external heatsink that simply clips off if need be.  All capacities have yet to be released but we are seeing lower pricing for the MP600 1TB version right now on Amazon which is so key in today’s SSD arena.

    Thanks for the review.

    Please answer, why you say “The Corsair MP600 Pro XT Gen4 NVMe SSD is the second best result we have ever received in testing OS data, just behind that of the Plextor M10P.”
    when the WD_Black SN850 makes this 15 GB OS-file transfer according to your test in 62 sec only!

    Can you explain how the wd black 850 achieves this, what no other companie’s ssd can do?
    The “older” 96-layer nand beats even the new 176-layer nand.

      The SSD you are referring to was tested with the AMD Test Bench and the drives compared in this result are all tested with the Intel Test Bench, as stated at the top of the chart. As for that result, that review fully explains our surprise and repeated testing with the same times over and over.

        No explanations or guesses how the SN850 achieves that 😉
        Any number of the MP600 Pro XT is higher; in some cases by a lot.
        I think I found the reason for that in another review: The big 281GB slc cache + controller optimized for 4kB IOs in the first run; second run it gets slower by a lot.
        Not normal thing to do I guess?

        Can you please explain if all/how many the ssd we see nowadays have
        1) static dedicated slc-cache
        2) pseudo slc-cache (taken portion from the tlc-nand)
        3) dynamic pseudi slc-cache (like 2), but dynamicall adapted, changing size if needed.
        If there are changes, how I know as a consumer?
