FADU Launches Industry Leading SSD Solutions Powered by SiFive RISC-V Core IP

SiFive, the leading provider of commercial RISC-V processor IP, and FADU, a fabless company developing solutions and systems for the memory and storage market, today announced the availability of FADU’s Annapurna SSD Controller and FADU Bravo Series Enterprise SSD, powered by SiFive’s industry leading 64-bit, E51 multicore RISC-V Core IP.

The FADU Annapurna SSD controller is the world’s first RISC-V based SSD Controller and provides the highest throughput (3.5GB) and IOPS (800K) among its peers, while consuming less than 1.8W active power. Powered by FADU Annapurna, the FADU Bravo SSD is the first 7mm low-power U.2 supporting dual port and offers 3-4X IOPS / watt greater efficiency, 30% lower power, and the most consistent latency QoS in its class. Despite consuming only 6-8W of active power, FADU Bravo easily outperforms competing solutions at 25W, due to its innovative design, advanced flash memory controller, and use of SiFive’s high-performance 64-bit embedded RISC-V Core IP.

“FADU is focused on building the most advanced memory and storage devices for our customers and addressing their ongoing needs,” said Jihyo Lee, CEO, FADU. “SiFive’s RISC-V Core IP was 1/3 the power and 1/3 the area of competing solutions, and gave FADU the flexibility we needed in optimizing our architecture to achieve these groundbreaking products.”

FADU expects to become a leader in the enterprise SSD market, particularly in the hyperscale datacenter. FADU is currently demoing its Annapurna controller and Bravo SSD at the Flash Memory Summit in booth 715, at the Santa Clara Convention Center.

“The flexibility, 64-bit, embedded and multicore features of the E51 RISC-V Core IP is ideal for the storage market and we’re excited to be closely partnered with FADU, who was able to quickly take advantage of RISC-V and deliver a true world-leading product,” said Jack Kang, Vice President of Product, SiFive. “SiFive looks forward to working with FADU as they continue to build next-generation products for the SSD industry.”
