FADU Technology Announces DELTA SSD Gen4 Platform for OEM and Hyperscale Data Center Storage

Santa Clara, Calif. – November 10, 2020 – FADU Technology is a fabless startup developing advanced flash storage technology to meet the ever-increasing data storage demands placed on OEM and Hyperscale Data centers. The company announced today the FADU DELTA SSD Gen4 Platform for next-generation flash-based storage.

FADU develops its Flash-based storage technology around generational platforms. Each platform supports various SSDs that are powered by a proprietary FADU Flash Memory Controller which enables the company to deliver storage solutions with the industry’s highest KIOPS/W. 

The DELTA SSD Gen4 Platform includes SSDs targeted at High Performance OEM Servers, OEM storage with Dual-Port capability, Hyperscalers with OCP Spec 1.0 compliance and E1.S form factor support, including all types of heat sinks, and Edge with low-power capability.

  • Full dual-port support                                         
  • SR-IOV and SGL support                                     
  • Enterprise storage feature set
  • Enterprise security                                               
  • QLC support                                                            
  • ZNS support
Cloud: Hyperscale and Edge (E1.S/M.2)

Lowest Power/IOPS
OCP 1.0 Spec Compliance
SR-IOV and SGL support
Multi-stream & ZNS
Exceptional QOS at low queue depth
QLC support

FADU’s Gen4 controller, the FADU FC4121, powers the FADU DELTA SSDs and is the industry’s second RISC-V based Flash memory controller, following FADU’s ground-breaking FC3081 Gen3 Flash Memory Controller.  The FC4121 is designed to take full advantage of the NVMe 1.4a/PCIe Gen4 x 4 host interface and dual-port functionality. It’s designed to interface with Low Latency XL-FLASH™, eTLC, cTLC and QLC Flash memory. Like its predecessor, the FC4121 microcode is fully customizable, enabling NAND vendors with both Floating gate and Charge Trap Flash and OEMs to customize their designs for workloads and have customized telemetry to optimize their supply chain.

The FADU architecture eliminates Thermal Design Power (TPD) issues that require other architectures to sacrifice performance by either under-powering or throttling back their storage devices. FADU’s DELTA SSDs deliver the optimal high-performance, low power and highest Quality of Service (QOS) needed for OEM server and storage and hyperscale cloud applications.


The initial DELTA SSDs will support 3D eTLC in popular U.2 and E1.S form factors followed by support for cTLC and QLC and the addition of the M.2 form factor. FADU DELTA SSDs will initially support Hynix V6 NAND followed by others.

FADU DELTA U.2 SSDs are ideal for OEM enterprise servers and storage applications while the FADU DELTA E1.S SSDs are ideal for hyperscale and Edge datacenters service cloud applications and storage. Both SSDs have industry-leading performance and power (KIOPS/W) and are approximately double the performance of the Gen3 BRAVO SSDs.
