Dahua NM high-speed memory card packaging is relatively simple, using the common design of memory cards. There is a memory card in the middle of the front, protected by transparent plastic, with Dahua logo, capacity specification, English name and transmission speed on it. There are corresponding English instructions and Chinese paper stickers on the back, with relevant parameter information on them.
I believe some people don't know much about Dahua brand. In fact, it is the second video surveillance provider with excellent technology in China. Dahua Storage, as a subsidiary, has launched many products, such as hard disks and memory cards, which have been well received by everyone. The recently launched Dahua NM high-speed memory card is specially designed for Huawei or HONOR. Authorized by Huawei technology, it can be well compatible with mobile phone systems.
Dahua NM high-speed memory card has three specifications: 64G, 128G and 256G. You can choose the right one according to the memory of the mobile phone. This time starting from 256G, one step at a time. After all, there are usually more photos and videos, and WeChat and QQ in mobile phones will take up more and more memory, starting from 10 G.
Dahua NM high-speed memory card is different from the common TF card in appearance, and it is smaller. People who often use TF card will not think that it is also a memory card when they see this card. Dahua logo, name, capacity and reading speed are printed on the front, which is clear at a glance; The layout of the back chip is also different, and the exposed metal sheet area is larger than that of TF card.
Dahua NM high-speed memory card is the same size as the Nano-SIM card of mobile phone, and the missing angle is the same. People who are not familiar with it think it is also a mobile phone card. However, the difference between the two can be well distinguished by the back. The middle fracture of the metal sheet of Dahua NM high-speed memory card is wide and flat, while the Nano-SIM card is narrow and inconsistent.
Dahua NM high-speed memory card can be compatible with the card slot on the SIM card holder of mobile phone. Just like installing the SIM card of a mobile phone, most smart phones now have two SIM card slots, so that one slot can hold the SIM card and the other slot can hold the SIM card, which does not affect each other and is convenient to use. There is no need to set another TF card slot.
Dahua NM high-speed memory card has a 3-year warranty, has certain waterproof and antimagnetic characteristics, is safe and secure to use, is authorized by Huawei technology, and is compatible with Huawei or HONOR system. Inserting the card holder with memory card and SIM card into the mobile phone can quickly identify and read the data in the memory card, which is quite convenient and fast.
Dahua NM high-speed memory card supports eMMC5. 1 protocol, with a reading speed of 93MB/s and a writing speed of 82MB/s, which is much faster than the common TF card. In order to avoid the lack of memory in the mobile phone, the default storage location of the mobile phone can be changed to a memory card, so that data such as photos or videos taken later can be directly stored on Dahua NM high-speed memory card without transmission through a computer.
I have configured a TF card for my mobile phone before, but it often pops up after a period of use, and I need to re-insert and restart my mobile phone every time to work normally. Also, it is very slow to read photos, videos and other files in TF card with mobile phone, especially when running the application software installed in TF card, which is quite depressing. Recently, Dahua NM high-speed memory card has been used for more than half a month, and there is no previous situation. The speed and stability of the memory card are good.
Generally, there is no slot for Dahua NM high-speed memory card in the docking station of notebook, and Huawei's special card reader is needed to support reading TF card and NM card, with Type-C interface and USB-A interface at both ends. Dahua NM high-speed memory card has a continuous reading speed of about 93MB/s and a writing speed of about 87MB/s in the test of CrystalDiskMark, which is basically consistent with the official data.
Dahua NM high-speed memory card has satisfactory overall performance, various specifications to choose from, Huawei patent authorization, good compatibility, support for 3-year limited warranty, good data reading and writing speed, support for mobile phone continuous shooting and 4K HD shooting, high cost performance, and convenient for mobile phone to expand memory.
