Slow. The main reason is that the speed is slow, especially if you really buy a 256G or 1t one, and then you take a lot of photos and videos. When searching for photos and videos, you will find that after scrolling quickly, the thumbnails may often not come out. .
There is no doubt that NM cards can be used in dual-SIM dual-standby mobile phones, but currently NM cards can only be used in Huawei series mobile devices. I believe many people, like me, often complain about the small storage capacity of mobile phones.
Whether it is a mobile phone with small storage or a mobile phone with large storage, it seems to be only a matter of time before the storage is close to full. Nowadays, WeChat APP has become a storage monster on mobile phones. The application of NM card can effectively solve the problem of storage expansion. In terms of price, the NM card is more expensive than the TF card, but its reading and writing are faster and more stable. Moreover, for the same model of mobile phone, the combination of the NM card and low-end storage is more cost-effective than the high-end alone.
For example:
Dahua NM memory card is the abbreviation of Dahua Nano Memory Card, so this is a Nano card, which is better than our traditional TF card (MicroSD card) should be small. This card has Huawei's patent authorization and is mainly for Huawei or Honor mobile terminals, mainly Huawei or Honor mobile phones, and is compatible with many models of Huawei or Honor, but not all, so before purchasing, you need to go Check to see if your phone or tablet supports it.
This memory card supports high-speed reading and writing. With the support of eMMC5.1 protocol, the reading speed is up to 93MB/s and the writing speed is up to 82MB/s. It also supports mobile phone continuous shooting and 4K high-definition video shooting. , that is, it supports smooth shooting.
This memory card comes in a variety of specifications. The more popular ones are 64G, 128G, and 256G. The one I tried is 256G. I usually like to take pictures and watch videos, so a larger memory card is better. In order to get it right at once, I chose the 256G one, which should be enough.
