Philson took the opportunity to show his controller in action E26 (PS5026-E26) which will power a large number of PCI-Express 5.0 SSDs. How could it be otherwise, the company tested its technology on a motherboard Hero Asus ROG X670E alongside an AMD Ryzen 7000 still in engineering sample form.
In essence, we have an adapter that takes advantage of the motherboard’s PCI-Express 5.0 x16 interface to connect an SSD formatted M.2-2580 that, combined with the use of memory chips 3D TLC NAND Flash Micron’s most modern, and its controller, managed to achieve read speeds of 12 GB/s while in writing it happened 10 GB/s (12,457/10,022 MB/s to be exact). When it comes to 4K random read and write, we’re talking about 1,310,000/1,160,000 IOPS.
The first-generation Phison E26 controller comes to life with a configuration of 2x ARM Cortex-R5 cores accompanied by special accelerators of the CoXProcessor 2.0 family. The controller can work with all current and future 3D Flash NAND memory types with ONFI 5.x and Toggle 5.x interfaces with data transfer speeds of up to 2400 MT/s. While Phison positions its PS5026-E26 for consumer and business PCs, it also supports U.3 connectivity, Single Root Input/Output Virtualization (SR-IOV), and Zone Namespaces ( ZNS).
Phison did not reveal when the first client SSDs based on PS5026-E26 controllers will be commercially available. However, last year it hinted that the first drives using its PCIe 5.0 x4 platform would hit the market. in the second half of 2022which probably means the end of 2022 next to AMD processors and motherboards, expecting the maximum performance of this first generation to be slightly lower than current tests, since should reach 14 GB/s.
