GK2101/2 SSD Controller


Product Overview

GK210x SoC is the first domestic high-performance low-cost SSD controller that supports 5Gbx4 PCIe or 6Gbps SATA interfaces and customized development with independent intellectual property rights in China. GK210x uses the world leading architecture design to guarantee the outstanding sequential read/write performance and compatibility with kinds of SLC, MLC, eMLC, TLC and 3D flash memories. The Special Error Correction Engine (Adaptive LDPC + Soft DSP) and RAID data protection mechanism in GK210x, combined with Goke’s own NANDXtra technology, could improve SSD‘s working life by five times. Based on controller chips, Goke provides widely types of storage products, which applied to enterprise server, cloud storage, data center, ultra high-speed data acquisition system and portable equipment, etc.
