On paper, Phison introduced the first PCIe 4.0 SSD controller in the market to sync with AMD Ryzen 3rd generation and X570 motherboard launch. One of its key features is the PCIe 4.0 support, giving access to speedy PCIe NVMe storage.
This was made possible via Phison PS5016-E16 controller. Now, Phison is readying its PS5018-E18 controller. The company will be sending out its samples by early next year. This was confirmed during Flash Memory Summit.
About the E19T Controller…
There is also the Phison PS5019-E19T. Unlike what the model number implies, its a lower spec of the E16 controller. This does support NVMe 1.3 standard on 28nm process. It’s reduced down to 4-channel support with 1.6w power draw and up to 2TB storage support. This continuous read/write support up to 3,750 MB/s and up to 440K/ 500K IOPs in random read/write speeds.
About the E18 PCIe 4.0 SSD controller…
Unlike the E16 which is designed with an older design, the E18 is an entirely new design.
The E18 will have three cores with its own CoXProcessor. With this, Phison can provide up to 7GB/s speeds with one million IOPs via its eight-channel design.
Recap of the E16 PCIe 4.0 SSD controller…
The older design used up to two ARM CORTEX R5 CPU cores. It uses the 28nm process and does support NVMe 1.8 specs via the PCIe 4.0 x4 connectivity and has 8-channel support. It supports up to 8 TB storage capacity. The E16 controller support up to max read/write speeds of 5,000/ 4,400 MB/s and maximum 750K/750K Random Read/Write IOPS at 2.6w. This will be Phison’s mainstream PCIe 4.0 SSD controller.
During the transition, Phison moved from 28nm Lithography towards 12nm process. The maximum storage capacity is 8TB. This PCIe 4.0 SSD controller will enable a robust feature set and provide higher throughputs, burst load and even enable Phison’s 4th generation error correction engine.
It should be interesting to see how PCIe 4.0 SSDs shape up. Silicon Motion also showed its PCIe 4.0 controller.
