The main brands currently on the market include Huawei, Leshaq, HP, Baiwei, Yizheng, Chaoshang, Jichu, etc.
As a high-performance external memory card, NM cards have relatively high requirements for production quality. In addition to Huawei's own production, Baiwei, a leading domestic storage brand, has also obtained the official patent authorization of Huawei's NM cards. Baiwei also has its own factory in Huizhou, with a strong production capacity of 70KK/month.
NM memory card is Huawei's world's first ultra-miniature memory card, which provides a more convenient way to store data. The specifications of Huawei's NM memory card and Nano SIM card are almost identical. You only need to use one Nano SIM card slot in a dual-SIM phone to expand the phone's storage.
In Huawei Mate 20 series mobile phones, you can put two NanoSIM cards or a single NanoSIM card + NM memory card to expand the storage space of the phone. NM memory cards solve a major pain point in future 100% full-screen mobile phone design.
More importantly, Huawei NM memory cards are very fast. The read and write speed of the memory card is directly related to the user's experience of browsing pictures and videos. When Huawei first designed the NM memory card, it set strict standards for reading and writing of no less than SDU3 (minimum write rate 30MB/s). speed.
