MyDigitalSSD BPX 480GB M.2 NVMe PCIe SSD Review

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.




Sequential read/write transfers max out at an impressive 2,997/2,410 MB/s. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity. Both figures are higher than listed manufacturer specs. The reason for this large difference in results vs. mfg. specs is because MyDigital's advertising specs are for incompressible data; ATTO uses compressible data. Phison's E7 controller is unique among NVMe controllers in that it handles compressible and incompressible data differently.


Sequential Write




The BPX and Patriot Hellfire perform almost identically because they are almost identically configured. The BPX and the 600p are priced similarly but perform quite differently. It's no mystery which drive is a better choice.


Sequential Read




The Hellfire and the BPX again perform similarly, but as we look at current pricing, the 480GB Hellfire will cost you at least $40 more than the 480GB BPX. When the data is compressible, the BPX has no trouble outperforming most of the competing SSDs in our test pool.




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 the total score. When evaluating NVMe SSDs, we are looking for a minimum total score of over 10K.








Anvil's scoring gives a good indication of a drive's overall performance. In terms of overall scoring, the BPX gives us what we are looking for. The BPX outscores the 950 Pro, Intel 750, and the Intel 600p. The Hellfire scores slightly higher, but not enough to matter.


(Anvil) Read IOPS through Queue Depth Scale




With our configuration, we are able to attain 209K random read IOPS at QD32. Keep in mind that this is our OS disk and it is 75% full.




The BPX, Hellfire, and 250GB 960 EVO all follow a similar performance curve at queue depths of up to 32. Intel's 600p display's inferior performance; once again showing why the BPX is clearly superior at a similar price point.


(Anvil) Write IOPS through Queue Scale




With our configuration, we are able to attain 192K random write IOPS at QD32. Keep in mind that this is our OS disk and it is 75% full.




Samsung's 960 EVO series SSDs display superior burst performance, but as you will see further on in the review, this doesn't necessarily translate to better moderate workload performance.


At low queue depths, the BPX takes a backseat to the majority of the SSDs in our test pool. At queues depths of 8-32, the BPX outperforms Samsung's 950 Pro, Intel's 750 and 600p.
