InnoGrit Starts Mass Producing YRS820 PCIe 5.0 Controller, Based on RISC-V Architecture
InnoGrit's low-wattage 12 nanometer IG5666 controller popped up on the T-FORCE GE PRO PCIe 5.0 SSD series earlier in the year, but attention has turned to another consumer-grade design. Parent company—Yingren Technology—is not well known outside of China, although its InnoGrit brand has started to make inroads within Western markets. The enterprise-level YRS900 PCIe 5.0 SSD controller was announced last September—this open-source RISC-V-based solution was designed/engineered to "align with U.S. export restrictions." According to cnBeta and MyDrivers reports, a new YRS820 controller has successfully reached the mass production phase. This is a PCIe 5.0 consumer-grade controller, likely derived from its big sibling (YRS900).
According to InnoGrit presentation material, their new model is based on: "RISC-V instruction architecture, adopts a 4-channel PCIe 5.0 interface, is equipped with 8 NAND flash memory channels, supports NVMe 2.0 protocol, has an interface transmission rate of 2667MT/s, can be paired with 3D TLC/QLC, and supports a maximum capacity of up to 8 TB." Company representatives stated that the YRS820 controller is destined to be fitted on high-end consumer parts—the AI PC market segment is a key goal, since the YRS820 is able to: "accelerate data processing for specific applications and have high stability, consistency and security." cnBeta highlighted some anticipated performance figures: "YRS820 achieves sequential read 14 GB/s, sequential write 12 GB/s, random read and random write up to 2000K IOPs and 1500K IOPs respectively." InnoGrit did not reveal a release timetable, since their latest consumer-grade controller is going through a validation process. The company is currently collaborating with domestic NAND flash memory and DRAM manufacturers, as well as other industry bodies.

Random writes are less of a problem, they are always several times faster than reads (because they can be cached) and generally there are fewer writes than reads.
Also, where has Samsung Z-NAND gone? It was many times more expensive than any other NAND-based enterprise SSD but its latency was incredibly low too.
