Introduction

 

MyDigitalDiscount's SBX series M.2 NVMe SSDs are much faster than any SATA SSD. To this point, the one thing SATA had in its favor was lower cost per gigabyte of storage than NVMe could offer. Now MDD's SBX is challenging SATA on the price front as well.

MDD's SBX pairs Phison's PS5008-E8 (E8) 4-channel 2-lane NVMe controller with BiCS 3 64-layer 3D flash to create a powerful yet inexpensive SSD capable of delivering performance that is up to 3X better than SATA has to offer.

 

MDD really made a name for themselves with their last major NVMe SSD, the MDD BPX. To this day it is still one of our all-time favorite SSDs. What made the BPX so popular was that it offered far and away the best value on the NVMe front.

MDD's SBX is following in the BPX' footsteps. Like the BPX was at the time, MDD's SBX is currently the lowest cost NVMe SSD on the market. The SBX represents the first time we've seen NVMe SSDs priced similarly to SATA.

 

Phison designed their E8 controlled SSDs to primarily compete with the likes of Intel's 600p Series. The SBX is designed to not only be cheaper than Intel's 600p, but at the same time deliver better performance despite being only a 2-lane device.

 

MDD's SBX is a Gen3 x2 NVMe SSD. Having 2-lanes instead of four like we typically see, means that the SBX is more power efficient than most 4-lane SSDs. It is also cheaper. The other side of the coin is that with only 2-lanes, the SBX doesn't deliver sequential performance that is as high as we are used to seeing from most 4-lane NVMe SSDs.

 

However, as you will see when we get to the numbers, MDD's SBX is no slouch on the performance front. In-fact, the SBX actually outperforms many 4-lane SSDs currently on the market. We already demonstrated this with our Phison E8 performance preview.

 

NVMe performance for the price of SATA sounds good to us, now let's see for ourselves what the SBX is serving up.
