SK hynix Gold P31 1TB NVMe SSD Review – Worlds 1st 128-Layer SSD Performs at an Amazing Price


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.



These results are just about the best we have seen from a PCIe 3 NVMe SSD to date.


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.The AS SSD results aren’t as appealing as we might like to see but do get a first look at read and write IOPS which appear to be in the general ball park of listed specs.




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.


  1. Just gone one yesterday to replace the OEM 256GB hynix SSD that came with my desktop.

    MUCH cooler, MUCH faster, especially on writes and what a bargain price for the performance, lifespan, excellent write perf, and its cool. The old drive would hit 60-80C, this is barely warm.

    Price this against a 970 or 8200 pro or black SN750 with a heatsink (you’ll want one with those, they run MUCH warmer!) and see what a bargain this is.

    • Yes it took them a bit to enter the retail market but i think they will do very well. Many are unaware that they have been commonplace in many laptops for some time.
