preface

Today, when buying mobile phones and tablets, their storage capacity is also one of the factors to choose. In particular, Apple products need careful consideration. 16G or 64G has become a difficult choice for Apple fans. However, with the emergence of wireless USB flash drives, this choice will be broken. DM smart phone wireless USB flash disk is one of the outstanding wireless USB flash disk products. It allows your mobile phone to freely transfer files and change the traditional storage mode, only to make storage simpler, more convenient and more useful, not limited to mobile phone systems and single use. The new intelligent storage concept is only to make the USB flash disk more suitable for your life.

Appearance: small and portable

The outer package of the product is made of black hard paper, with gold "DM" printed on the front (Shenzhen Liangxin Technology Co., Ltd.'s brand: DM）。

The model of this wireless USB stick is WFD035, which increases the battery capacity compared with previous generations of products.

A long manual, a Micro USB cable and a host computer are the same for most digital products.

The DM smart phone wireless USB flash drive is made of ordinary polyester plastic in appearance, and is wrapped in plastic with a golden border in the middle. It has a general texture, but it is less than 27g, which is very convenient to carry.

The back of the DM wireless USB flash drive is the product APP QR code, scanning and downloading the client. This time, the capacity is 32Gb, and other capacities are available.

The whole body has a Mico USB interface, which is used for charging, memory reading, and functions the same as the Mico USB interface of the mobile phone.

The most striking place on the front is the round key, which is also the key to start. It looks like fingerprint identification of mobile phones, but only has the key function.

Some people must ask how big this is and whether it is a big piece. In fact, it is only one circle larger than four coins, and its thickness is only 1 cm. So when you go out and put it in your bag or pocket, you don't need to worry about it. It is small and exquisite.

It can be charged with a computer USB interface or a power bank. The DM wireless USB flash drive has a battery capacity of 1400mAh. It takes 2 hours to fully charge from 0% to 100%. To be honest, the charging time is a little long. I hope it can speed up the charging speed.

Press the round key for three seconds to enter the power on state. The DM wireless USB stick adopts two wireless connection modes, 2.4G and 5G connection schemes. The default is 2.4G network mode when power on

Double click the button again to switch to 5G network mode, and the indicator light turns green and blinks

APP experience: watching movies and surfing the Internet

When using the APP for the first time, you need to search the wireless network starting with "WFD". However, the wireless network name here cannot be modified. After the connection is successful, the APP will automatically search the wireless USB flash disk. This search process takes about 2 to 3 seconds.

Some people may ask if the mobile phone is connected to this wireless USB flash disk, and the mobile phone is unable to access the Internet. Don't worry about this. After connecting to the DM wireless USB flash disk, the APP has a setting for connecting to the Internet. You can use this wireless USB flash disk as a repeater to connect to other WiFi, so that the mobile phone can watch dramas and surf the Internet without error.

After connection, the APP file management system manages the files in the DM wireless USB flash disk: videos, pictures, music, documents, etc.

To view the files in the DM wireless USB flash disk through a mobile phone, when viewing from pictures to music, the reading speed is relatively fast. However, when watching a video for fast forwarding, it is still inevitable that the video will get stuck, but there is no stuck phenomenon during the whole viewing process.

There are three ways to preview pictures. Like the way to view pictures on a computer, there is no stuck delay in picture viewing, and the browsing and viewing are smooth. Therefore, it is suitable for users with small memory or 16G iPhone to use it to store photos taken.

As the most important privacy of individuals, mobile file backup can also be uploaded to DM wireless USB flash disk via APP. It supports backup of address book, photo album, pictures, music and other types of backup. Compared with other third-party network backup, it can be done anytime and anywhere.

Of course, you can also download the contents of the DM wireless USB flash disk to your mobile phone at the same time. For 2.4G and 5G networks, there is no obvious difference in video viewing or download speed. However, in terms of distance, the signal in the 5G network environment is stronger than that in the 2.4G network. Of course, for this portable wireless USB flash disk, it is not significant.

Of course, compared with the relevant products in the market at present, the speed of the sentence "I am afraid of throwing myself away" is OK.

Test: comparison of theoretical and actual reading and writing speed

Other third-party software is tested as follows:

It can be seen that the maximum reading speed will reach 30MB/s, while the writing speed will be about 10MB/s. However, this is only a theoretical value, and the actual results will be biased. The average data results of the author through several actual tests are as follows:

Reading speed: 26MB/s

Write speed: 6MB/s

In general, the write speed is still slow. Although the USB3.0 theoretical transmission speed is as high as tens of megabytes per second, it is actually far from this value. Therefore, we hope to improve the data write speed.

Summary: This DM wireless network smart USB flash disk is really a good device for those friends who have small mobile phone storage capacity, like sharing photos and videos, office data sharing and backup, and has high cost performance.

However, one thing that is not particularly convenient here is that you need to install an APP to view the content in the USB disk. If you want to share the content in the USB disk, the other party also needs to install it. Therefore, it is recommended to add a Web access method. In addition, the content in the USB disk needs to be put in files through mobile phones or computers, I hope you can download some files by connecting to the internet cache like a router.
