Phison: PCI-E 5 controller spotted on X670E with AMD Ryzen 7000 CPU
In a first video, Phison showed a new M.2-2580 PCIe 5.0 x4 SSD that relies on the PS5026-E26 controller and offers extremely high write and read rates. The SSD has been validated for testing on both a Zen 4 and Alder Lake S platform. Read more about this below.
In the course of Computex 2022, Phison announced a collaboration with AMD and Micron, in which all three companies combine their fastest technologies to equip the Zen 4 with adequate working memory and flash memory using the 5 nm process. In addition, the company has presented the new PS5026 PCI-E 5.0 SSD controller, which on paper is said to have twice the performance of its predecessors with PCI-E 4.0. Now the manufacturer has presented its new SSD with a PS5026-E26 controller in a video.
Partners in the PCI-E 5.0 ecosystem: AMD, Micron and Phison join forces
It was tested on an Asus ROG X670E Hero with a prototype Ryzen 7000 chip. While more than 14 GB/s with sequential write and read performance is expected for the enterprise area with PCI-E 5.0, the desktop area doesn’t seem to be too far behind. For validation, the test SSD was on a special Phison board that was plugged directly into a PCI-E x16 slot and, in addition to the new controller, also had Micron’s latest 3D TLC NAND memory.
In a first run in CrystalDiskMark, the new SSD achieved almost 12,500 MB/s in read rate and still very fast 10,000 MB/s in sequential write performance. Compared to the maximum achievable 7,000-7,500 MB/s of PCI-E 4.0, these are extremely fast write and read rates that show how much potential PCI-E 5.0 has. Phison also tested the new SSD on an Intel platform consisting of an Asus Z690 Aero D and an Alder Lake-S CPU, covering all platforms that previously offered PCI-E 5.0.
