Colleagues gently lifted their legs and directly kicked off the 8G USB flash drive that accompanied me for more than 5 years. It was finally easy to use two broken USB flash drives to save the information, but still need to buy a new USB flash drive to store Frequently used data, after all, for an old driver, some information is more private (you know).
Usually need to be responsible for the company to repair the computer to do what the system, and the need to save some PS material and product photos, the capacity can not be too small, now USB3.0 has been popular, in order to speed up the best 3.1, so used to copy Some fragmented files can also be faster, and finally the face value is higher, and it deserves me!~~~~
The brand still prefers Kingston, the trust of the old users is relatively high, anyway, tea shop buyers are not too worried about fakes, and eventually chose this Kingston HXS3/64GB USB3.1 HyperX Savage U disk.
Kingston HXS3/64GB read speed up to 350MB/s 64GB USB3.1 HyperX Savage U disk 369 yuan Jingdong direct link cut to the chase, post the picture!

Unpacking
Lanyard
When receiving the express delivery, the box was thrown away directly. Only physical objects can be taken. The U disk is completely sealed and can only be opened with scissors. It contains U disk, manual, stickers, and a lanyard. The color value is quite high. The red X part is metal. The black shell is a frosted plastic. The hand feels very good. The weight is heavier than the average one. The tail part near the lanyard is the trapezoidal indicator light. The interface represents an interface that is 3.0 or more, but if you compare carefully, you can still find that the interface is slightly different from the general 3.0 interface.
The price is so expensive USB3.1 interface standard U disk, the manufacturers write the maximum writing speed of 180M / S, in the end how do you need to actually test how to test the use of computer configuration: CPU Core I5-4670, 8G DDR3 memory ASUS B85-PRO motherboard, the target file is stored in 128G SSD hard drive, USB3.0 interface.
The actual test results: a large number of fragmented file copy speeds can begin to reach 24M/S, behind can only reach about 17M/S or so, the speed is good, but a lot worse than expected.
A small number of large file copies
In order to test large files, more than 10 movies were directly copied. This time the speed is very good. The copy speed can reach approximately 90M/S in the early stage and 70M/S in the later stage.
to sum upKingston's U disk 64G memory even if the game or a separate system is stored without problems, the shell is strong and durable, high value, copy the file speed can reach 20M/S, large files can reach 80M/S, for the general The use of daily work is fully qualified and the price is slightly higher, but it is acceptable.
Industry Control Circuit Board
Industry control printed circuit boards (PCB)
1. For industrial control, special or general-purpose circuit board, the bottom circuit is completed, and IO is reserved. After buying the industrial control circuit board, the input and output ports reserved on the circuit board are connected to the user's own device, such as motor, solenoid valves, sensors, thus completing the function want to accomplish.
2. The special circuit board is a board specially designed for a certain function, such as the temperature control circuit board. After buying it, the input port is connected to the thermocouple, and the output port is connected with a heating contactor or a solid state relay to control the heating device to complete the temperature control. There are flow control boards, motion control boards, etc.
3. The universal control board, most of which can be programmed, after the user's own secondary development, completes a specific function, and has a wide range of uses. For example, plc is a general industrial control board. After the user writes the program and compiles the input, various functions can be completed. Digital input, analog input port, high-speed counter port, digital output port, analog output port, and some also have communication function.
