Huawei's mobile device storage weapon to break through the bottleneck —— A brief comment on Dahua NM memory card

Although the capacity of mobile phones and tablets is much larger now, the video and picture files are getting bigger and bigger, and the APP is getting bigger and bigger. Even if the storage capacity is large, it will encounter the problem of insufficient storage after a long time. However, mobile phones and tablets are not like computers, just adding a hard disk. Sometimes, inserting a TF card may solve the problem, but sometimes, even inserting a TF card cannot solve the problem, and there is no extra TF card. How can we break the storage bottleneck of mobile phones and tablets at this time? If you use Huawei or Glory's mobile phone, then maybe you have another way to break the bottleneck of mobile phone or tablet storage, that is Dahua NM memory card.

Dahua NM memory card is the abbreviation of Dahua nano memory card, so it is a nano card, which is smaller than our traditional TF card (MicroSD card). This card has Huawei's patent authorization, and it is mainly aimed at Huawei or Glory's mobile terminals, mainly Huawei or HONOR, and is compatible with many models of Huawei or Glory, but not all. So before buying, you need to check whether your mobile phone or tablet supports it. This memory card supports high-speed reading and writing. EMMC5. 1 protocol support, the reading speed is as high as 93MB/s, and the writing speed is as high as 82mb/s. It also supports the shooting of mobile phone continuous shooting and 4K HD video, which means the shooting is smooth. There are many specifications of this memory card, among which 64G, 128G and 256G are popular. I experienced 256G, and I usually like to take photos and watch videos, so the memory card is still a little bigger. In order to get it in place at one time, I chose 256G, which should be enough.

The packaging of Dahua NM memory card is fine, because the card is relatively small, so cover it one layer at a time. This plastic box is the innermost part, which can protect the memory card well. From this angle, we can also see the quality of this product, even the packaging is so serious, the performance of the memory card will certainly not be bad. It is said that Dahua NM memory card has been strictly tested by the certification laboratory, and the product performance, quality, compatibility and reliability are guaranteed.

Open the last plastic package and you will see the memory card. You will find Dahua NM memory card, which is almost the same as the SIM card of mobile phone. The front of the card is divided into two parts by white and dark red. Dahua's LOGO is on the white background, and the patterns of gray @ and D are very distinctive. Below is the product name. You can see the product name and capacity of NM card and 256GB, and the speed of 90 MB/s, so Dahua NM memory card can be used as video or photo memory card. We often take photos or videos with our mobile phones or tablets. Although the storage capacity of a single photo or video is not large, with the passage of time, the demand for storage capacity can not be underestimated. Just Dahua NM card is fast enough to store videos or photos directly. The back of the card is the serial number of the product and the contact point of the card, which looks different from the contact point of the TF card or SD card of the mobile phone and close to the SIM of the mobile phone.

We put a TF card and Dahua NM memory card into the card slot of a mobile phone, and we can clearly see the size difference between the two cards. Dahua NM memory card only occupies the position of a SIM card, while TF card is much larger. Originally, I wanted to use one of Huawei's mobile phones, but I suddenly found that it was not supported. So before buying, be sure to confirm the product model. At present, this memory card only supports some mobile phones of Huawei or Glory. If only all mobile phones could support it.

Fortunately, Huawei's tablet can support. When it is loaded into the card slot, the capacity will expand in an instant. Seeing 232GB of memory card space, my blood is boiling in an instant.

Move some MP3 players and see how fast they move. It feels good. 2.5 GB media files move in 4 minutes, which is really fast. No one is at this speed. It's definitely no problem to take photos and videos like this.
