China's First PCIe 5.0 SSD Controller from InnoGrit Enters Mass Production

[AleksandarK]

During the China Chip Storage Future 2023 Storage Industry Trend Summit, Yingren Technology, widely recognized as InnoGrit outside of China, announced the initiation of mass production of its enterprise-level YR S900 PCIe 5.0 SSD controller. Marking a significant breakthrough, the YR S900 stands as China's first domestic PCIe 5.0 SSD controller. Operating on an open-source RISC-V architecture, the YR S900 is engineered to align with U.S. export restrictions, ensuring a seamless design and manufacturing process of the SSD controller. While Yingren Technology remains discreet about the specific process node to produce the YR S900, it's known that the controller embodies a versatile design, with compatibility extending to mainstream NAND from eminent manufacturers, and exhibits an impressive synergy with NAND from Yangtze Memory Technologies Corp (YMTC).

The YR S900 is a quad-channel controller, offering sequential read and write speeds peaking at 14 GB/s and 12 GB/s, respectively, and is equipped with InnoGrit's third-generation ECC engine to optimize 4K LDPC encoding and decoding. This collaboration with Kioxia's XL-Flash results in a low 4K random read latency of 10us, highlighting its potential to deliver higher data throughput, increased stability, and extended service life. The YR S900 encompasses a comprehensive feature set, including FDP, SR-IOV hardware virtualization, CMB, and a range of data encryption algorithms. While the mass production of the YR S900 underscores a monumental stride in SSD solutions within China, it remains to be seen whether adopting this new Chinese technology will enter markets beyond China.

Very nice photo. This one’s going into my collection.

will enter markets beyond China

If SSDs are advertised as having high speeds and prices are competitive, many will just grab solutions based on this controller by simply ordering directly from Aliexpress. Of course warranty in this case will be questionable, other than claiming a refund in case the drive is DOA, but many wouldn't mind to give it a try.

Finally another Gen5 controller beyond that overheating trunk from Phison

Nice! now we have 2 gen5 controllers that overheats!

Whose chip did they place on the photocopier...

Because it's gen5 it don't mean it's fast enough to get hot.

You say that like any of Innogrit's solutions have been cut and paste to date.. They've actually been fairly innovative.

Also, there is literally only one PCIe 5 controller on the market to copy, and this sure isn't a copy of that.

You can copy a design without copying it. Some call it "inspiration". But if it's performant and stable, the world could do with another PCIE controller.
