The first generation main control E16 of group connection achieves continuous reading and writing of up to 5.0gb/s and 4.4gb/s. Now ps5018-e18 is the second generation of pci4.0 master control, continuous read performance of 7.4gb/s, continuous write performance of 7GB / s. < / P > < p > not only has the read speed soared, but also the key write performance has exceeded 7GB / s. At present, it is the only SSD master with both read and write performance reaching 7GB / s. < / P > < p > in terms of random performance, the random read and random write of ps5018-e18 master controller have both reached 1000K IOPs, and the performance of million IOPs used to be only available for server level SSDs, and now it is easy to implement. < / P > < p > in other aspects, the ps5018-e18 master controller adopts TSMC 12NM process, multi-core architecture developed by cluster, 8-Channel 32 CE, supports nvme 1.4 specification, supports DDR4 and lpddr4 cache, supports 8tb capacity and power consumption of 3.0w, providing first-class performance and energy efficiency. Pan Jiancheng, chairman of qunlian, said that when peers in the market were just starting to release their first PCIe 4.0 SSD product, qunlian and its partner amd had jointly released the PCIe 4.0 ecosystem and had been ahead of the market in mass production for more than one and a half years. < p > < p > for the new generation of flagship pci4.0 SSD control chip, ps5018-e18, can give full play to the bandwidth of pci4.0 and provide high-speed performance of more than 7.4gb/s to terminal customers. It is not only a demonstration of the technology capability of the group connection accumulated for 20 years, but also represents that the group alliance will lead the technology and development direction of NAND control chip in the future.
