The products of pcie4.0 SSD are quite rich, but the overall price is still on the high side. After all, it is still in the initial stage, and the solutions are too few. The consumer grade SSD products are all based on the ps5016-e16 master control system of Qun. Today, Weigang released a brand new < / P > < p > this time, Huirong sm2267 was demonstrated more than a year ago, positioning the mainstream market, supporting four flash memory channels and nvme 1.4. The official nominal continuous read-write speed can reach 4GB / s and 3gb / s, and the random read-write speed can reach 400k IOPs. < / P > < p > on top of it, there is a high-end sm2264, which supports eight channel flash memory, and the performance can reach 7GB / s, 6GB / s and 700k IOPs. < / P > < p > the newly released XPG gamma S50 Lite is a standard m.2280 specification, covering with high temperature resistant aluminum heat sink, which can reduce the temperature by 20%, and has been treated by wire drawing process, which has more texture. < / P > < p > the capacity can be 1TB or 2TB. It supports PCIe 4.0 x4, nvme 1.4 and dynamic SLC cache. The maximum nominal continuous read-write speed is 3.9gb/s and 3.2gb/s, and the maximum random read-write speed is 490k IOPs and 540k IOPs, which is much higher than the previous nominal capacity. Obviously, Weigang and Huirong have made further adjustment and optimization. In terms of service life, < / P > < p > the average time between failures is 2 million hours, the maximum write volume is 1480tb, and the warranty period is five years, which is equal to 0.4 full disk writes per day, typical TLC.
