After a long preview of the roadmap and the show, silicon motion finally officially launched the company’s next-generation PCIe 4.0 nvme SSD controller. Although the PCIe 3.0 X4 is still the mainstream of the current consumer m.2 SSD market, Huirong still hopes to break through the performance limit of the previous generation interface by virtue of the high-end sm2262 and the more mainstream sm2267 / 2267xt master controller. < / P > < p > first of all, sm2264, which focuses on high-end, is the successor of sm2262 (EN). Although the number of supported NAND channels is still 8, the maximum speed has doubled to 1600 MT / s. < / P > < p > in addition, the master integrates four arm cortex-r8 cores. As a comparison, SMI’s client / consumer nvme master only integrated two cores. < / P > < p > like most high-end pcie4.0 master controllers, Huirong also uses a smaller TSMC 12NM FinFET process node (the previous generation was 28nm planar process), and the energy efficiency ratio has been significantly improved. < p > < p > it is clear that sm2264 will compete fiercely in the market with the flagship consumer grade SSD master of Samsung and Western Digital, and the E18 master controller to be launched by Phison. < / P > < p > although qunlian has launched E16 master controller for consumer market for a long time, the newly launched pcie4.0 master controller can further develop the potential of pci4.0 X4 interface. At present, Huirong sm2264 PCIe 4.0 X4 nvme SSD master controller is providing samples to SSD manufacturers. As to when the final product will be launched, it is not known at present. < p > < p > as for the more mainstream market, Huirong hopes to replace the previous sm2263 / 2263xt with sm2267 / 2267xt. For entry-level SSDs, this will help them improve their performance to the level that only high-end PCIe 3.0 SSDs could achieve. < p > < p > among them, sm2267xt is the DRAM free version of sm2267, and CE support has been cut off by half. However, one of the advantages of this method is that the package size becomes smaller, which is suitable for small devices such as m.2230. In terms of process, sm2267 (XT) is still based on a more affordable but relatively large 28nm process node. At present, the two main controllers have been put into mass production. It is believed that the supply chain will soon launch retail products, such as the Weigang gammix S50 Lite sample that AnandTech preemptively experiences. < p > < p > it is reported that sm2267 will compete with the previous generation 8-channel master such as qunlian E12 and the newer 4-channel solution in SK Hynix gold P31. It is expected that the consumer grade SSD segment market will usher in a more hot sales situation in 2021. < / P > < p > as for the sm2267xt without DRAM cache, the master controller will compete with the entry-level nvme SSD master control such as qunlian e19t, and the terminal product price is expected to be equal to that of the SATA drive. < / P > < p > in addition, these low-cost nvme masters are also very popular in the SSD market. After all, the bandwidth of USB 3.2 is only 20 GB / s, and the actual performance requirements are not so important, unless you want to give full play to the strength of lightning 3 port (40 Gbps).
