The MyDigitalSSD SBX is one of the first SSDs to use a controller designed for low-end NVMe SSDs. The combination of the Phison E8 controller and Toshibas 64-layer 3D TLC has allowed the MyDigitalSSD SBX to be one of the cheapest NVMe SSDs on the market, priced near mainstream SATA SSDs but with higher performance than any SATA SSD can offer.

MyDigitalSSDs business model revolves around selling drives based on Phison reference designs. Like any other small SSD brand, MyDigitalSSD lacks the resources to develop their own SSD controller or even write their own firmware from scratch. The way MyDigitalSSD distinguishes themselves from the many competing brands is by offering drives for substantially lower prices and by being one of the first to market with new controllers from Phison. The SBX checks both boxes: it is priced below the Samsung 860 EVO SATA SSD, and it hit the market in December 2017 as the first Phison E8 drive to ship and one of the earliest retail SSDs to feature Toshiba/SanDisk 64-layer 3D NAND.
