Adata and Biwin Choose Rainier PCIe Controller From Innogrit for SSD

Innogrit Corporation announces the adoption of its Rainier PCIe (IG5236) controller by Adata Technology Co Ltd. for design into XPB Sage and by Biwin Semiconductor (HK) Company Limited for design into NW200, both PCIe Gen 4 NVMe SSDs in an M.2 2280 form factor.

The Rainier SSD controller is an addition to the company’s line of SSD controller chips which includes its Gen 3 SHASTA, SHASTA+, and Gen 4 Tacoma product offerings.

AnandTech and Tom’s Hardware have reported the firm’s Rainier controller as an advance over the existing SSD controllers on the market, targeting the high-end client and entry-level datacenter markets.

Rainier is a SSD controlles fabricated in TSMC (Taiwan Semiconductor Manufacturing Company, Limited)‘s 12nm FinFET process. It has 8 NAND channels that can run at up to 1,200MT/s, fast enough for next gen NAND, and can support up to 16TB of storage.

Rainier-based SSDs achieves sequential read speed of over 7GB/s and write speeds greater than 6GB/s, saturating the PCIe 4 x4 interface. It also adds enterprise-oriented features like multiple namespace support and SR-IOV virtualization, while client-oriented power management is still supported, with idle state at under 50mW and sleep state at less than 2mW.

“We are very excited about ADATA’s XPG Sage SSD passing the 7GB/s milestone using Innogrit’s Rainier (IG5236) as the SSD controller. This new Adata offering promises significant speed and IO/s improvements over all the current PCIe 4.0 SSDs,” said Ms. Shalley Chen, president, Adata. “We are pleased with the continued partnership with Innogrit and share their vision of bringing best-of-class performance to computing and gaming markets.“

“Throughput from storage devices has always been a bottleneck in computer systems. A Gen 4 PCIe NVMe SSD doubles the throughput of a Gen 3 PCIe NVMe SSD and greatly improves overall system performance,” said Larry Li, VP engineering, Biwin. “Demand for PCIe Gen 4 SSD will increase dramatically in year 2020. Innogrit’s Rainier controller provides unprecedented performance and power efficiency that enables us to unleash the potential of Gen 4 PCIe interface in a power sensitive M.2 platform.“

Adata’s XPG Sage PCIe Gen 4 SSD and Biwin’s NW200 SSD recently show-cased at CES 2020 are among the first to use the company’s Rainier controller. The preliminary CrystalDisk results from the live demo units showed sequential read and write speed of 7,240 and 5,395MB/s respectively. Future firmware release will increase the write rate to over 6,000Mb/s.

“We are extremely pleased to collaborate with ADATA and Biwin in bringing their PCIe Gen 4 NVMe SSDs to market and the opportunity it provides us to showcase our advanced controller technology,” stated Dr. Zining Wu, CEO, Innogrit. “Innogrit’s long term goal is to position itself as the high-performance controller of choice for client and enterprise storage markets. Establishing Innogrit’s design credentials, our first controller, IG5208 ‘Shasta’ is already in mass production with full turnkey reference SSD designs available. Evolving from Shasta, advanced feature sets incorporated into our Shasta+ and Rainier product offering are being well received in the SSD marketplace,” continued Dr. Wu.
