Phison Electronics: the transmission speed of PS5026-E26 is up to 13GB/s
At the CES 2022 exhibition earlier this year, Phison released a new generation of PCIe 5.0 controller PS5026-E26, which is aimed at enterprise-level and high-end desktop gaming SSDs and is a flagship product in the PC market. Later, it was announced at Computex 2022 that it would work with its partners AMD and Micron to build a PCIe 5.0 ecosystem, and to welcome the advent of the PCIe 5.0 SSD era.
Although many people have focused their attention on the PS5026-E26, the new generation PCIe 5.0 controller can achieve a maximum data transfer speed of 13 GB/s. However, Phison pointed out in its annual report that among the three key solutions it will provide next, there are two PCIe 4.0 controllers, namely PS5025-E25 and PS5020-E20.
According to Phison, the PS5025-E25 will use an external DRAM design with a maximum data transfer speed of 7200 MB/s, making it the best choice for extremely fast gamers. PS5020-E20 is an enterprise-level SSD controller, which supports a maximum capacity of 32TB and supports a variety of special functions in enterprise-level applications. It will be a suitable choice for server system integrators.
Previously exposed information shows that Intel’s upcoming Raptor Lake still has only 16 PCIe 5.0 lanes directly connected to the CPU. This means that if a PCIe 5.0 SSD is used, it will have to share the PCIe 5.0 lanes used by the discrete graphics card. Compared to Intel’s limited support for PCIe 5.0 SSDs, AMD’s AM5 platform is clearly a more suitable platform.
However, in the future, PCIe 5.0 SSD will be limited to the choice of enthusiasts, and ordinary users will still choose PCIe 4.0 SSD. With this in mind, Phison is right to continue to develop high-performance PCIe 4.0 controllers, the PS5025-E25’s maximum data transfer speed has increased by 200 MB/s over the existing PS5018-E18, and features such as power management have been updated.
