For SSD makers to continue pushing sequential speeds higher, the industry needs to start moving to PCIe 4.0, a change that AMD plans to make with their Ryzen 3rd Generation processors and their Zen 2 EPYC platform. Phison is already preparing for the day that PCIe 4.0 is available, preparing a controller that can meet the PCIe 4.0 specification, using 4x lanes of PCIe 4.0 bandwidth to deliver sequential read/write speeds that can exceed 4,000MB/s. These speeds already exceed the theoretical limits of 4x PCIe 3.0 lanes, never mind the limitations of the standard in real-world terms.  Phison's new controller is called the PS5016-E16, which was running using the PCIe 4.0 interface over a PCIe 3.0 x16 to PCIe 4.0 x8 converter, which allowed the SSD to interface with an Intel-based test system using an i7-8700K and an ASUS ROG Strix Z370-F Gaming Motherboard. In the future, Phison hopes to accelerate their SSDs by 10% using firmware optimisations and offer a further 10% performance boost by utilising faster BiCS4 NAND, with hopes to achieve performance levels of 4,800MB/s sequential and deliver 900,000 random IOPS. AMD will be the first CPU manufacturer to market with PCIe 4.0 compliant processors and motherboards, with Ryzen 3rd Generation products releasing in Mid-2019. Yes we need more speed!

Specs: AMD 2920X Threadripper, Corsair MP510 M.2, 64GB Corsair RGB Dominator,  ASRock X399 Taichi, Corsair 1000D, EVGA RTX 2080 Black

    Love it! Though now that I have raid 0 nvme, I feel like there are other bottlenecks. Mostly software induced.

    That I could load a game on a drive reading 500MB/S and on one reading 5000MB/s and get nearly identical load times is wild.
