PCIe 4.0

At FMS 2024, Phison gave us the usual updates on their client flash solutions. The E31T Gen 5 mainstream controller has already been seen at a few tradeshows starting with Computex 2023, while the USB4 native flash controller for high-end PSSDs was unveiled at CES 2024. The new solution being demonstrated was the E29T Gen 4 mainstream DRAM-less controller. Phison believes that there is still performance to be eked out on the Gen 4 platform with a low-cost DRAM-less solution.
