Intel has introduced PCI-E 5.0 on the 12th generation Core, and AMD will also be added to the next-generation Ryzen 7000 series, and will provide PCI-E 5.0 M.2 interface, so it is time for SSD manufacturers to prepare for a new generation SSD solution, Phison has now publicly demonstrated its own PS5026-E26 PCI-E 5.0 SSD master control.
Phison's SSD sample using E26 master control works on the ASUS ROG X670E HERO motherboard. This SSD uses Micron 3D TLC flash memory with a capacity of 1TB. Its continuous reading speed reaches 12.5GB/s. The continuous writing speed is 10GB/s, and the current PCI-E 4.0 speed is up to 7.5GB/s. The performance improvement is quite obvious. But this speed was measured under QD16. QD1, which has a greater impact on daily applications, has a continuous read of only 4GB/s and a continuous write of 8.8GB/s. The random read and write performance of QD1 is actually the same as that of PCI-E 3.0. SSD is not much different.
What’s interesting is that the sample displayed by Phison does not have any radiator installed. Previously, E16 and E18 of PCI-E 4.0 generated a lot of heat and basically required a radiator to work. I don’t know if E26 is real. It reduces heat generation and does not require a radiator. The E26 main control uses two ARM Cortex-R5 cores and three dedicated CoXProcessor 2.0 accelerators, which are produced using TSMC's 12nm process.
SSD using Phison E26 controller is expected to be launched later this year, and it is speculated that it will be synchronized with AMD's new generation platform.
