In the practical test, the flash memory reading and writing of Huawei Mate 40 Pro can reach a speed twice as much as that of UFS 3.1. The flash memory printed with the logo of Hisilicon was firstly found in the disassembling process of Mate40 RS Porsche Design. It may indicate that Huawei has studied and developed its own flash memory.
It is known that Huawei Mate 40 Pro, 40 Pro+ and Mate40 RS Porsche Design adopt a new flash memory (or sfs 1.0) that Huawei developed by itself. However, Huawei has never disclosed it officially or publicized it at any launch event, so the related technical details are still unknown.
