Phison has presented the PS5026-E26 controller, which will guide NVMe SSDs into PCIe 5.0. The company showcased their new controller by manufacturing a 1 TB TLC SSD. 

Direct access technologies based on Microsoft's DirectStorage API are accelerated by two ARM Cortex-R5 cores and three CoXProcessor 2.0 accelerators built using TSMC's 12 nm technology. Phison's reference SSD reaches sequential read rates of over 12 GB/s in CrystalDiskMark and sequential write speeds of 10 GB/s - a 70% performance boost compared to the world's fastest PCIe 4.0 SSDs, which reach 7 GB/s sequential speeds.

Phison's proof-of-concept SSD has a PCB and connector footprint incompatible with M.2 2280 slots. SSDs based on Phison's PS5026-E26 controller is slated to ship later this year, with AMD's 600-series chipsets for its AM5 platform.
