Phison doesn't seem to be done with its PCIe Gen 4 SSD controllers yet as a listing over at IOL has revealed the upcoming PS5020-E20 controller.

Phison's PS5020-E20 High-End Gen 4 NVMe Controller To Power Data Center Solutions

Currently, Phison offers its PS5016-E16 mainstream and PS5018-E18 high-end PCIe Gen 4 NVMe SSD controllers for the consumer segment. Phison has also confirmed specifications and details of its upcoming PS5026-E26 controller, its first PCIe Gen 5 SSD controller. As of right now, Phison offers up to 7400 MB/s Read and 7000 MB/s Write speeds for their top-end Gen 4 products while Gen 5 is posed to bring speeds of 12,000 MB/s Read and 11,000 MB/s Write.

But while the specifications and initial details have been revealed, the majority of the market, especially the consumer segment, shouldn't expect PCIe Gen 5 NVMe SSDs till the very end of 2022. The same goes for the Data Center segment and it looks like Phison has planned a high-end and intermediate solution that servers between the E18 and E26, and that should be the PS5020-E20.

There are currently no details mentioned regarding the PCIe Gen 4 E20 controller from Phison but it could be likely that Intel's recently leaked Optane P5810X and P5811X could be using the new controller. As for the listing over at University of Hampshire's InterOperability Laboratory, it looks like the new controller will support the NVMe 1.4 protocol and come in U.2 form factor and that points out to solutions designed for data centers and cloud computing rather than consumer PCs. The following specs sheet from Computerbase shows the main differences between the current controllers and what one can expect from E20:
