The Chinese company Yingren Technology, known internationally under the InnoGrit brand, announced the start of mass production of its YR S820 consumer controller for PCIe 5.0 SSDs.
Last year, the company began mass production of the YR S900 controller for enterprise-grade PCIe 5.0 SSDs. The new YR S820 controller for the consumer market is similar in many ways. Similar to its predecessor, it is designed for the Chinese market and uses the same open RISC-V architecture, which is not subject to US export sanctions.
According to Yingren Technology, the new YR S820 consumer controller supports various AI functions. The company didn't go into detail, but said the YR S820 is great for AI-powered PCs and features “AI technology for data acceleration that reduces latency and improves performance on certain tasks.”
Yingren Technology did not say who exactly produces the YR S820 controller or what process technology it is based on. Although the company noted that the chip uses the RISC-V architecture, it did not specify the number of cores in the controller or their clock speed. From the Yingren Technology presentation it is known that the YR S820 supports four PCIe 5.0 lanes and up to eight NAND flash memory channels. It is also known that it can work with 3D TLC or QLC NAND flash memory chips with transfer rates of up to 2667 MT/s per channel and be used in SSDs up to 8 TB.
On paper, the new product may well compete with controllers from Phison and Silicon Motion. As part of the presentation, Yingren Technology demonstrated test results for SSDs based on YR S820 and 232-layer X3-9070 TLC NAND flash memory chips from local manufacturer YMTC. The drive provided sequential read speeds above 14.2 GB/s and sequential write speeds above 12.4 GB/s. At the same time, its performance indicators for random read and write operations were 2 million and 1.5 million IOPS, respectively. The memory chips in the test SSD operated at a speed of 2400 MT/s, so the YR S820 still had some reserve left.
Yingren Technology also states that the YR S820 will be able to provide such performance figures as part of consumer drives without the use of active cooling systems in the latter. How close this statement will be to the truth will be shown by the first SSD models based on it. However, all high-speed PCIe 5.0 drives require efficient cooling. Otherwise, under prolonged loads, they overheat and lose performance.
It is noted that Yingren Technology is currently sending samples of the YR S820 controller to local NAND and DRAM memory manufacturers. Although the company confirmed that it has already begun mass production of the controller, it did not specify when the first products based on it can be expected to go on sale.
