At present, most of the pcie4.0 nvme SSDs on the market have the problems of high power consumption and high heating, so it is difficult to put them into use in compact devices such as laptops. In addition, the product based on OEM solution of group connection (E16 master control) has been used by many manufacturers for at least half a year. The reason for this is that most SSD controllers were originally designed for the application of pci3.0. It is obvious that there is still a large space for optimization to upgrade the workload of supporting PCIe 4.0. < / P > < p > previously, the group Alliance launched the first PCI 4.0 nvmessd master controller (E16) in the market, but it actually adopts a hybrid design – on the basis of E12 master control in the era of pci3.0, it eliminates the components of pci3.0 and adds the part that can handle the connection of pci4.0. < / P > < p > for the enterprises pursuing rapid listing, the public version scheme of grouplink E16 is obviously time-saving and labor-saving. Unfortunately, due to the lack of optimization, its performance of heat and power consumption also limits the promotion of pcie4.0 nvme SSD to more platforms. < / P > < p > since then, we have been waiting for the launch of the optimized second generation of PCIe 4.0 nvme SSD master, such as E18, which is due to be launched later this year, and E19, which was shown during the industry exhibition. < p > < p > in addition, Huirong and its partners also exhibited a full range of solutions at Computex 2019 last year. < p > < p > during this year’s Consumer Electronics Show (CES 2020), Weigang launched two pcie4.0 nvme SSDs, which are mainly controlled by Huirong new, focusing on better heating and energy efficiency adjustment. < / P > < p > in addition to the sm2264 high-performance master for desktop computers, there are also sm2267 controllers for notebook platforms with medium energy efficiency. < / P > < p > it should be noted that although the drive is designed with four channels instead of eight channels, DRAM and SLC caching can still guarantee high-end performance. < / P > < p > in addition, thanks to the new master controller with better energy efficiency, the temperature of gammix S50 Lite series products is still about 20% lower than that of competitors, and supports LPDC error correction, raid engine, and AES 256 bit encryption. < / P > < p > if you are interested, you can choose 1TB / 2TB capacity version, and the price is $150 / 300 (about 1015 / 2030 RMB). The manufacturer provides a five-year limited warranty (nominal write volume 1480 TBW), and the launch time in North America is October 1.
