MyDigitalSSD BPX Pro M.2 NVMe SSD Review - 240GB, 480GB, 960GB Tested!

Subject: Storage
Manufacturer: MyDigitalDiscount

MyDigitalDiscount doesn't seem to have been satisfied with their performance BPX line or their value SBX line, and have now launched a BPX Pro, which looks to carry the budget pricing of the SBX while offering performance *higher* than the original BPX. How much faster is the BPX Pro than the BPX? That's what this review sets to find out, so let's get to it.

With the label peeled back, we find the Phison E12, coupled to Toshiba BiCS3 TLC NAND. PCBs are single sided up to 480GB. 960GB (and 2TB - not in this review) employ a different PCB with additional DRAM and two more flash packages on the flip side.

Read on for the results and conclusion!

Results:

Details of our test suite and methodology/process are available here.

Random performance looks pretty good, and progresses neatly as capacity increases. This is especially noteworthy for the 960GB model, which surpasses the 1TB 960 EVO in both reads and writes!

Sequentials are also respectable, with burst writes beating the Samsung part (more on this further down, when we look at cache performance).

View Full Size

With a mixed workload, we see that the BPX Pro roughly doubles the write throughput, and is able to scale reads with capacity even in the face of those background writes.

...Samsung is still able to service this workload faster, but the BPX Pro is certainly closing here.

240GB writes at nearly 1GB/s, with TLC speeds running at 300 MB/s. Cache amount is inconsistent, but there were a few 25GB stretches in there.

View Full Size

480GB cached writes approach 1.9GB/s, dropping to 600 MB/s. Maximum cache observed was 40GB, which oddly took place at the highest write duty cycle portion of the sequence.

The 960GB model cached writes run at 2.9GB/s, dropping to 1GB/s once the cache is depleted. While the cache amount ran upwards of 50GB, this figure should be higher, and cache performance across all three capacities tested was not as consistent as expected. Further, there should have been more cache available at the two far ends of these charts. The first pass (leftmost section) takes place after a full 10 minute idle. The second after 5 minutes. There is another 5-minute wait before the last pass. These areas should have seen the highest available write cache.

Pricing and Conclusion:

BPX Pro

  • 240GB   - $75   - $0.31/GB (Amazon)
  • 480GB   - $130 - $0.27/GB (Amazon)
  • 960GB   - $260 - $0.27/GB (Amazon)
  • 1920GB - $520 - $0.27/GB (Amazon)

The MyDigitalSSD BPX Pro turned out to be a surprisingly performant SSD, especially given its budget-like pricing. While the company is still relatively new, they have proven themselves across several generations of products, so the 5-year warranty should offer sufficient peace of mind. Overall, the BPX Pro offers good performance at a competitive price, and should be strongly considered, especially for budget-minded system builds.

Why is this labeled as PCIe 3.0 x2? This is clearly a x4 SSD.

Yes, very odd since the specifications list it as PCIe 3.1 x4

Is the BPX just regular mlc drive? I don’t quite remember you have reviewed that parts.
Well this BPX pro and SBX are decent for their price points.

Would like to see intel 660p drives along with evo drives when reviewing nvme drives on the lower end of pricing, the 660p is just hard to beat

You're right. In this case, I just ran out of slots for our standard charts, since I wanted to keep the non-Pro BPX's and two Samsung units in there for comparison.

they should have tortured it. i dont want to buy one and suddenly see negative reviews on it. this is a company i dont trust yet.

Our test suite is quite hard on the drive being tested as far as preconditioning goes, but the results are based on paced workloads that are more realistic and better represent actual use.

I've been using their drives for a few years and I like them a lot. I started with their x2's and progressed to the x4's when I updated my cpu/mobo. Check out the history of the company, the founder's roots and how they do no advertising in order to keep costs down. They are a private company so they only answer to themselves and not share holders. I too was hesitant at 1st because they were somewhat unknown. The risk paid off. They are the proverbial thorn in the backside of other manufacturer's. Lastly, each purchase was followed up with an email that included discount codes for future purchases (mydigitaldiscount).

I am thinking of getting the 240 GB of this or the non-pro. Is the extra $15 worth it?

November 1, 2018 | 11:07 AM - Posted by Allyn Malventano

Tough call on that - the performance is faster, but that non-Pro unit at the smaller capacity is an even better bargain. If you're worried about performance at all then I'd go for the Pro.

How's this compare to the Crucial P1 1TB for about $50 less on Amazon? I've not run across the P1 in my surfing, but I do trust the Crucial band and $50 less is a good chunk...

I was eager to use these drives In my newest build and my early testing how been very close to Allyn's scores. Used the 460 BPX for the O/S and the 960 BPX for collecting raw video data when editing home video. I left the labels on for warranty was sowewhat concerned about the heat transfer through the labels but a rep said there made of special film that will allow for transfer of heat.
