Performance Comparisons – Client QD Weighted
These results attempt to simplify things by focusing on what really matters – the Queue Depths that folks actually see when using these products. A dimension is eliminated from the previous charts by applying a weighted average to those results. The weights were derived from trace recordings of moderate to heavy workloads, which still ended up running closer to QD=1-2 even on a slower SATA SSD. The intent here is to distill the results into something for those wanting 'just the facts' to grab and go when making their purchasing decisions. Don't be alarmed by the low figures. Remember, these are low queue depths – the place where these SSDs actually operate when in use by those not just running benchmarks all day!
The first thing to consider is just how close all of these random read (blue bar) results are. Sure the 960 EVO wins, but everything else is close. Even the 860 EVO is close, and that is using a SATA interface! For random reads, we do note an expected falloff at the smaller capacities, with the exception of the 960.
For sequential transfers, there's just no beating a solid PCIe 3.0 x4 SSD like the Samsung 960 EVO, though the rest of the field is decently quick given the lower costs of these parts.
This % read sweep chart shows the random QD weighted results between full reads and full writes. We look for a smooth curve here and all SSDs behave as expected with no surprises.
“The SBX uses the Phison
“The SBX uses the Phison PS5008-E8 controller, not the PS5008-E8T (dramless), so we find NANYA / Micron flash accompanying the controller on each part.”
Is this supposed to be NANYA / Micron DRAM?
LOL yup. Fixed, thanks!

I have a bpx… I would have
I have a bpx… I would have sent it back compared to my samsung ssd if i needed the money. Building a PC, sure buy this. Upgrading, anything less than a 1TB just doesn’t seem to add much value. About the only thing it does noticeably faster is unrar. At least with 1TB, you could put a few games on it since games are now 100GB each.
anyways, nice review.
Great in depth review.
Great in depth review. Thanks for bringing new products like this to us. I am definitely interest in getting a 500 or 1 TB for my next build.
I’m still using spinning
I’m still using spinning rust, and I can multitask while the lappy boots up by gettng my coffee ready during the process. Whenever they decide to make a 500GB SSD/1TB hard-drive hybrid drive I’ll become interested. I still like laptops that come with CD/DVD/Blu-ray drives as that can be swapped out for a hard/SSD drive caddy also.
Is MyDigital a Chinese firm?
Is MyDigital a Chinese firm? Where would you have to send their products for RMA if worst were to happen?
Their website shows their
Their website shows their location as in Oswego, NY, and they have a US toll free number for customer service.
i still rather get something
i still rather get something from westerndigital. at least i know t hey stand behind their stuff.
How would performance be
How would performance be affected on a system with PCIe 2.0? I appreciate the power efficiency and cost saving of using PCIe 3.0 (2x), but I’m considering using one of these drives to update an older system that only has PCIe 2.0. I’d be using an m.2 to PCIe adapter. It would be going into a 16x slot running 8x,but as far as I can tell, it will run at 2x speed, which tops out well below the speed of this drive. A drive with 4x should still have plenty of overhead, even at PCIe 2.0 speeds.
