Final Thoughts

When Phison first envisioned their E8 controller they set out to accomplish several things. First, they wanted to create the most affordable NVMe drives on the market. Going with two PCIe lanes and four channels was the best path to accomplish this feat. But, it would still need to be faster than other value-oriented SSDs even with a 2-lane disadvantage.

Next, Phison wanted to produce an NVMe SSD that could challenge SATA in pricing. This is probably the biggest hurdle because it's not in Phison's hands to do so. This would have to come from vendors. Naturally, the one to do it is MyDigitalDiscount. They are the only source for NVMe SSDs that are priced like SATA.

The SBX isn't the only E8 powered SSD on the market. Kingston's A1000 is another. Both the SBX and the A1000 perform identically, but the A1000 is priced much higher than the SBX. And with the SBX you get full drive capacity. This means not only is the SBX much cheaper than the A1000, you get between 8 and 64GB more capacity from MDD's SBX.

Looking back at our results, it's clear that Phison did deliver a 600p killer as they hoped to accomplish - despite a 2-lane disadvantage. Cheaper and faster wins every time. Not only is the SBX faster than the 600p it is also faster than WD's first generation Black PCIe SSD. Additionally, if we use our PCMark 8 results as a marker, the SBX is faster than ADATA's SX8000 and Plextor's M8Se at the same capacity points.

So, what do we have in MyDigitalDiscount's SBX? An NVMe SSD that is priced like SATA but delivers up to 3x the performance of SATA. Win. The SBX is faster, cheaper and more enduring than Intel's popular 600p. Win. The SBX is faster than many 4-lane NVMe SSDs. Win. The SBX comes in the most popular form-factor - a single-sided M.2 x2280. Win.

All those wins do matter, but what matters most is user experience. The SBX delivers there as well. It is noticeably more responsive than anything SATA has to offer. That's important because SSDs like the 600p actually do not deliver a user experience that is better than the best SATA has to offer. We are happy with our user experience while running the MDD SBX as our system disk, which is why MyDigitalDiscount's SBX is TweakTown Recommended.
