Later, when I think about it, if there is a USB flash drive with dual interfaces, I can easily store photos to my phone, and when I need to use them, I can easily transfer them to my computer. At this time, I searched for my needs on gearbest, and I was pleasantly surprised that there were indeed some of these products.
Thousands of choices, I chose the PNY family products, before bought their gold stick USB disk, it has been very good to use, but the capacity is not enough need to upgrade a large capacity. In addition, the new notebook is equipped with two lightning 3 interfaces, so it is the 256GB version of the PNY USB3.1 dual-interface USB disk.
To tell you the truth, gearbest logistics is really nothing to say, less than a day's time has arrived, a word is: come on, open the package, let's look at the product directly!
The outer package of the PNY USB3.1 dual-interface U disk is very simple, and it can be clearly seen on the package that the total capacity of the U disk is 256GB.
The volume of the whole U disk is very small, a metal rotating shell can well cover the two interfaces, the U disk is also equipped with a hole for lanyard, wearing a beautiful lanyard can not only improve portability, but also prevent loss.
The blue interface indicates the identity of its USB 3.1s.
The two interfaces are Type-C and Type-A, which can meet the current interface needs between smart phones and computers.
Can also be put in the pocket, go out to carry super convenient!
Both interfaces of this USB disk support file transfer, which is not very convenient for friends who transfer files frequently on their mobile phones and computers.
After we have seen the overall appearance of the flash drive, let's take a look at its actual speed.
In terms of capacity, the actual capacity is 230 GB, which is quite reasonable. Because there are some differences between the manufacturer's capacity algorithm and the system algorithm, the manufacturer calculates the capacity according to 1000KB=1MB, while the system calculates capacity according to 1024KB=1MB.
In terms of reading and writing speed, it is enough to use the most popular AS SSD, although there are many other testing software, but the results are more or less the same.
The software test shows that the write speed is about 110M/s, and the read speed is about 224m. The actual speed is slightly higher than the official standard data, which is quite adequate for many occasions of daily use.
Indeed, only the test data will be a little abstract, so let's just use it to transfer the file! The transferred file is a large-capacity mp4 video, which tests the continuous writing speed of the USB disk.
Directly copy to the U disk, from the actual speed, the write speed will be about 50MB/s, basically do not need to wait a long time, but also can meet the needs of daily video transmission.
To tell you the truth, the emergence of PNY USB3.1 dual-interface U disk does meet my daily frequent file transfer needs, and the design of dual interface does make me a lot more convenient. Even when I use my laptop, I can use Type-C interface to lend U disk to colleagues, or when others use it, I don't worry about incompatibility, because there is also a Type-A interface.
However, the 256GB version of my evaluation is only 289 yuan, in fact, such a work artifact is not too expensive, like friends, I suggest directly on the highest version.
