Nowadays, smartphones are becoming more and more powerful, bringing a lot of convenience to people’s lives and work. However, with the increase in data such as photos, videos and installed applications, the memory of mobile phones is gradually not enough. . Many people will increase the memory of their mobile phones by deleting some data, but this only treats the symptoms but not the root cause, and the same problem will still occur after using it for a period of time. Recently, I bought a Dahua NM high-speed memory card, which can give Huawei or Honor mobile phones expansion space. Let’s take a look at what kind of experience it has.
The packaging of Dahua NM high-speed memory card is relatively simple and adopts the common design of memory cards. There is a memory card in the middle of the front, which is protected by transparent plastic. It has Dahua logo, capacity specifications, English name and Transfer speed. There are corresponding English instructions on the back, and there is also a Chinese paper sticker with relevant parameter information.
I believe some people know little about the Dahua brand. It is actually the second largest video surveillance provider in China and has excellent technology. As its subsidiary, Dahua Storage has launched many hard drives and memory cards. Products such as these have been well received by everyone. The recently launched Dahua NM high-speed memory card is specially designed for Huawei or Honor mobile phones. It has Huawei technology authorization and is better compatible with mobile phone systems.
Dahua NM high-speed memory cards are available in three specifications: 64G, 128G, and 256G. You can choose the appropriate one according to the memory situation of your mobile phone. This time, I bought the 256G model, which is perfect in one step. After all, we usually take a lot of photos and videos, and WeChat and QQ on the phone will take up more and more memory, often starting at more than 10 GB.
The appearance of Dahua NM high-speed memory card is different from that of commonly used TF cards. It is relatively smaller. People who commonly use TF cards will never think that it is also a memory card when they see this card. The Dahua logo, name, capacity, reading speed and other information are printed on the front, which is clear at a glance; the chip layout on the back is also different, with more metal sheet area exposed than the TF card.
The size of Dahua NM high-speed memory card is the same as the Nano-SIM card of mobile phones, and the notches are the same. People who are not familiar with it think that it is also a mobile phone card. However, the difference between the two can be better distinguished through the back. The metal piece of the Dahua NM high-speed memory card has a wider and flat break in the middle, while the Nano-SIM card has a narrower and inconsistent break.
Dahua NM high-speed memory card is compatible with the card slot on the SIM card tray of the mobile phone. It is the same as installing the SIM card of the mobile phone. Most of the current smart phones have two SIM card slots, so that One card slot holds the SIM card, and the other card slot holds the SIM card. They do not affect each other and are easy to use. There is no need to set up a separate TF card slot.
Dahua NM high-speed memory card has a 3-year warranty, has certain waterproof and anti-magnetic properties, and is safe and secure to use. It also has Huawei's technical authorization and is compatible with Huawei or Honor mobile phone systems. Insert the card tray with the memory card and SIM card installed into the mobile phone, and you can quickly identify and read the data in the memory card, which is very convenient and fast.
Dahua NM high-speed memory card supports the eMMC5.1 protocol, with a reading speed of up to 93MB/s and a writing speed of 82MB/s, which is much faster than commonly used TF cards. In order to avoid insufficient memory on the phone, you can change the default storage location of the phone to the memory card, so that the photos or videos and other data taken in the future can be directly stored on the Dahua NM high-speed memory card, without the need to transfer it through a computer.
I have configured a TF card for my phone before, but after using it for a period of time, it often pops up, and I need to re-insert and restart the phone every time to normalize. In addition, it is relatively slow to read photos, videos and other files in the TF card with a mobile phone. Especially when running applications installed in the TF card, lags often occur, which is quite frustrating. Recently, I have been using Dahua NM high-speed memory card for more than half a month, and the situation is completely different from before. The speed and stability of using the memory card are both good.
Generally, the docking station of notebooks does not have a card slot for Dahua NM high-speed memory cards. It requires a Huawei dedicated card reader. It supports reading TF cards and NM cards. There are Type-C cards on both ends. interface and USB-A interface. In the CrystalDiskMark test, the Dahua NM high-speed memory card has a continuous reading speed of about 93MB/s and a writing speed of about 87MB/s, which is basically the same as the official data.
The overall performance of Dahua NM high-speed memory cards is quite satisfactory. It has a variety of specifications to choose from. It has Huawei patent authorization and good compatibility. It supports a 3-year limited warranty and is suitable for most Huawei and Honor mobile phones. Data The reading and writing speeds are good, and it supports continuous shooting and 4K high-definition shooting on mobile phones. It is cost-effective and can easily expand the memory of mobile phones.
