MyDigitalSSD BPX M.2 NVMe SSD Review (480GB) – An Unmatched Value

PCMARK 8 STORAGE

The SSD Review uses PCMark 8’s Storage test suite to create testing scenarios that might be used in the typical user experience. With 10 traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games, it covers some of the most popular light to heavy workloads. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices. After an initial break-in cycle and three rounds of the testing, we are given a file score and bandwidth amount. The higher the score/bandwidth, the better the drive performs.

PCMARK 8 STORAGE RESULTS

In PCMark 8 the MyDigitalSSD scored 5082 points and averaged 555.03MB/s in bandwidth.

This score beats out the 1TB Samsung 960 EVO by a hair and puts it in line with the other E7 powered SSDs we have tested.

PCMARK 8 EXTENDED STORAGE WORKLOAD CONSISTENCY TESTING

For our last benchmark, we have decided to use PCMark 8 Extended Storage Workload in order to determine steady state throughput of the SSD. This software is the longest in our battery of tests and takes just under 18 hours per SSD. As this is a specialized component of PCMark 8 Professional, its final result is void of any colorful graphs or charts typical of the normal online results and deciphering the resulting excel file into an easily understood result takes several more hours.

There are 18 phases of testing throughout the entire run, 8 runs of the Degradation Phase, 5 runs of the Steady State Phase and 5 runs of the Recovery Phase. In each phase, several performance tests are run of 10 different software programs; Adobe After Effects, Illustrator, InDesign, Photoshop Heavy and Photoshop Light, Microsoft Excel, PowerPoint and Word, as well as Battlefield 3 and World of Warcraft to cover the gaming element.

  • PRECONDITIONING -The entire SSD is filled twice sequentially with random data of a 128KB file size. The second run accounts for overprovisioning that would have escaped the first;
  • DEGRADATION PHASE – The SSD is hit with random writes of between 4KB and 1MB for 10 minutes and then a single pass performance test is done of each application. The cycle is repeated 8 times, and with each time, the duration of random writes increases by 5 minutes;
  • STEADY STATE PHASE – The drive is hit with random writes of between 4KB and 1MB for 45 minutes before each application is put through a performance test. This process is repeated 5 times;
  • RECOVERY PHASE – The SSD is allowed to idle for 5 minutes before and between performance tests of all applications. This is repeated 5 times which accounts for garbage collection; and
  • CLEANUP – The entire SSD is written with zero data at a write size of 128KB

In reading the results, the Degrade and Steady State phases represent heavy workload testing while the recovery phase represents typical consumer light workload testing.

PCMARK 8 RESULTS

As you can see, performance is recorded in terms of Bandwidth and Latency. Bandwidth (or throughput) represents the total throughput the drive is able to sustain during the tests during each phase. Latency, at least for the purposes of PCMark 8, takes on a different outlook and for this, we will term it ‘Total Storage Latency’. Typically, latency has been addressed as the time it takes for a command to be executed, or rather, the time from when the last command completed to the time that the next command started. This is shown below as ‘Average Latency’.

PCMark 8 provides a slightly different measurement, however, that we are terming as ‘Total Storage Latency’. This is represented as being the period from the time the last command was completed, until the time it took to complete the next task; the difference of course being that the execution of that task is included in ‘Total Storage Latency’. For both latency graphs, the same still exists where the lower the latency, the faster the responsiveness of the system will be. While both latency charts look very similar, the scale puts into perspective how just a few milliseconds can increase the length of time to complete multiple workloads.

For a more in-depth look into Latency, Bandwidth, and IOPS check out our primer article on them here.

AVERAGE BANDWIDTH (OR THROUGHPUT)

These results show the total average bandwidth across all tests in the 18 phases. In this graph the higher the result the better.

AVERAGE LATENCY (OR ACCESS TIME)

These results show the average access time during the workloads across all tests in the 18 phases. In this graph the lower the result the better.

Over the course of its PCMark 8 Extended run, the MyDigitalSSD BPX displayed enthusiast class performance that mirrored that of other E7 powered SSDs. It is nearly neck and neck with both the Corsair Force MP500 and Patriot Hellfire. It delivered fairly consistent performance during the steady state and recovery rounds. It averaged just under 500MB/s during the recovery section, which is the same as the Patriot Hellfire, but the extra cache on the Corsair Force MP500 gave it an advantage over it. Just as we have seen before, the latency profile is well managed, but not quite as good as Intel 750, OCZ RD400, or Samsung PCIe SSDs.

Great to see a review of this by you.
Did you conduct any tests for throttling?
My main beef with M.2s in general is how they heat up and drop down to 2x speeds.
I’ve only used Samsung XP / 950Pro and Plextor.
Have seen this in Towers and 1U/4U chassis.
I buy them for smaller footprint builds, but even 2x speeds allow the higher random iops.
Hoping somebody makes one that doesn’t slow down from streaming.
Thanks

Team Group is announcing a gaming M.2 SSD called the T-FORCE CARDEA. It has a cooling module atop the drive that they claim reduces temps by at least 15% and mitigates throttling. TSSDR should be posting press release coverage of this in the next day or so.

Excellent to hear. The MSI X270s address this but that Dog won’t hunt…

Your 30 GB transfer test is a bit of a giveaway-looks like a Toshiba built-possibly
My Digital firmware.
If they’re willing to sell at lower margins than the other clones-They’re the one
to buy…………………………………….

So is it good compare to other ssds ? I like the sound of the enterprise support modules

Please read the report as many of the tests are direct comparison with other SSDs.

Hi, the ssd is faster when the data is compressable, because of the nature of the controller?

Les@TheSSDReview

SSDs compress data when it is being stored which provides higher write speeds than data that is not easily compressed.

this ssd is much better value compare to 960 evo?

Largely due to this review, I chose the 240GB MyDigitalSSD BPX over a Corsair using the same controller that was on promo on Newegg. While I was about to pull the trigger on the latter, switched to Amazon & thankfully found this one. Performance wise, on a ASRock Z97 Extreme6 MB, although using a Sintech PCIe adaptor with a small fan for extra cooling, and would had purchased the Lycon or Addonics one w/out the fan if the Sintech model weren’t available. Because in the native Ultra M.2 slot (just as mSATA), these SSD’s will get toasty then begin to… Read more »

My first one was so good…..that I had to get another of the 240GB version, was priced the same. Wanted the larger, although pricing jumped by $25. In reality, don’t need that large of an OS drive, have many high performance HDD’s & various models of 120-128GB SATA-3 SSD’s awaiting action again. Just felt that any extra unallocated space (minimum of 10% recommended for most) would had boosted performance & drive longevity by the controllers having lots of unused space to work with. Note that some SSD’s (not limited to NVMe) has inaccessible space for this purpose, so manual over… Read more »
