Alibaba's T-Head unit, responsible for the design and development of in-house IC design, has announced the first domestic SSD controller based on the PCIe 5.0 specification standard. Called the Zhenyue 510, the SSD controller is aimed at enterprise SSD offerings. Interestingly, the Zhenyue 510 is powered by T-Head's custom Xuantie C910 cores based on RISC-V instruction set architecture (ISA). Supporting the PCIe 5.0 standard for interfacing, the SSD controller uses DDR5 memory as a cache buffer. 

Regarding the performance, there are no official figures yet, but the company claims to have 30% lower input/output latencies compared to competing offerings. T-Head claims the SSD has an IO processing capability of "3400 Kilo IOs per second, a data bandwidth of 14 Gbytes/s, and an extremely high energy efficiency of 420 Kilo IO per second for every Watt".
