The FADU FREE™ EC800F is FADU’s first enterprise NVMe SSD. FREE, standing for “Fast”, “Random access”, “Energy efficiency” and “Economics”, represents the values that FADU wants to deliver through its products. The EC800F, the first product of FREE™ series, is an NVMe 1.2 compliant PCIe SSD that comes in HHHL AIC form factor. The EC800F offers 3.2TB of user-addressable capacity and consumes a maximum 35W of  active power during operation. It is the best performing SSD, with up to 5GB/sec of sequential read throughput and 5GB/sec of sequential write performance provided via the PCIe 3.0 x8 connection. Random read performance peaks at over 1,100K IOPS, and it also offers a sustained 4KB random write performance of 400K IOPS(500K IOPS in case of OP 44%). 

The EC800F shows a bleeding-edge performance. 
Its sequential read throughput touches 5GB/sec and random read IOPS exceeds 1 million. Its write performance is even more surprising. The EC800F significantly outperforms the market benchmarks in both sequential and sustained random write operation. 

Due to the intrinsic characteristics of flash memory, handling flash is becoming more complicated than it seems. Especially, writing to flash is much more challenging than read from flash. During the write operation, SSD controller and FTL do many things behind the scene to guarantee reliable data processing and not to shorten the life of flash memory. If all these jobs could be done without sacrificing performance and resource, overall performance will be enhanced greatly and economically. This is the goal that FADU has tried to achieve through a new architecture.

The EC800F has just a single FPGA controller.
It has a one-PCB design and a single Xilinx Kintex Ultrascale FPGA (Field Programmable Gate Array) which handles 16 of 16nm cMLC NAND packages, each of which contains 16 of 128-Gbit dies. In its default configuration, EC800F provides 3.2TB of LBA space with 4TB of raw NAND capacity and user can configure the size of LBA. Re-programmability of FPGA and micro-code based implementation make it easy to customize the EC800F to support another type of NAND including 3D NAND and/or add many attractive features on the fly. 8GB DDR4-2400 DRAM, with assistance of memory access engine, accelerates time-consuming DRAM access and the 4 electrolytic capacitors will hold up enough power to protect not-yet programmed data in the event of a sudden power loss.

FPGA provides more programmability but its speed is lower and it consumes more power than ASIC (Application Specific Integrated Circuit). However, the EC800F offers the topmost level of performance using a single FPGA. For better performance with lower resource, FADU plans to develop ASIC-version of SSD during 2017. The next ASIC-version of enterprise SSD will be built on the same architecture as EC800F and features 3D NAND. Performance will rise up to 6.2GB/sec of both sequential read and write and 1,600K/750K of random read/write IOPS within a maximum 18W of power consumption.
