For consumer storage, CES 2020 brought a new wave of competition for PCIe 4.0 SSDs and promise of faster portable SSDs, but the most intriguing product demo was from Enmotus. They are planning a profound change to how consumer SSDs work, ditching drive-managed SLC caching in favor of host-managed tiered storage.

Enmotus is a well-established provider of storage management software. Their most familiar product to consumers is probably FuzeDrive, a limited edition of which is bundled with recent generations of AMD motherboards as AMD StoreMI. This serves as AMD's answer to Intel's Smart Response Technology (SRT) and Optane Memory storage caching systems. Enmotus also has enterprise-oriented products in the same vein. Their new MiDrive technology builds on their existing tiering software to manage a combination of SLC and QLC NAND on a single consumer SSD.
