Version and / or Patch Used: 3.05


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products. When evaluating ATTO performance we focus on the drive's performance curve.






The M8PeY meets or exceeds factory sequential specifications on both platforms. The Intel platform has a major advantage at 4K write transfers. Both platforms exhibit the same drop in performance at 48 and 64MB transfers.


Sequential Write




Graphing the performance curve shows the commanding lead that the Intel has over AMD's Ryzen platform. Comparing performance to the rest of the SSDs in our test pool shows the M8PeY is outperformed by all but Intel's 600p.


Sequential Read




The M8PeY performs similarly on both platforms when reading sequential data. This time the M8PeY outperforms both of the Intel SSDs that we included in our test pool. The M8PeY delivers a higher sequential read speed than Samsung's 950 Pro, however, the 950 Pro has a much better performance curve.




Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16. When evaluating performance with Anvils, we focus on total score. When evaluating NVMe SSDs we are typically looking for a minimum total score of over 10K.










The M8PeY can't hit 10K on either platform. It comes close on our Intel platform, but falls way short on our Ryzen platform. Most of the scoring difference between the platforms stems from Ryzen's inferior random write performance. In terms of overall score, the M8PeY is able to outscore the 950 Pro, and Intel's 600p.


(Anvil) Read IOPS through Queue Depth Scale






With our Intel platform, we are able to attain 168K random read IOPS at QD32. With our AMD Ryzen platform, we are able to attain 166K random read IOPS at QD32. Keep in mind that this is our OS disk and it is 75% full.




The M8PeY performs similarly on both of our testing platforms. The Intel platform maintains a slight performance advantage at lower queue depths. All of the competing drives in our test pool, with the exception of the Intel 600p, are delivering better performance.


(Anvil) Write IOPS through Queue Scale






With our Intel platform, we are able to attain 186K random write IOPS at QD32. With our AMD Ryzen platform, we are able to attain 189K random write IOPS at QD32. Keep in mind that this is our OS disk and it is 75% full.




At queue depths below 32, the M8PeY as expected performs significantly better on our Intel platform. Random write performance on Ryzen platforms is where the greatest performance disparity in comparison to Intel platforms will manifest itself throughout our testing.
