What is the difference between a black gel USB flash drive and a chip USB flash drive?

1. The structure is different: the black colloid U disk is composed of two parts, that is, the black colloid + shell. The chip USB flash drive is a traditional USB flash drive, and the internal structure can be seen when the shell is disassembled. There are PCB boards inside.

Chips, crystal oscillators.

and other elements. 2. Waterproof performance: The black gel U disk shell can be replaced, but because it is bonded with super glue, it is not easy to remove the shell.

Obviously, the black colloid is sealed, naturally waterproof, shockproof, and more flexible to use. The waterproof and shockproof ability of the chip USB disk is weaker.

3. Reading and writing speed: Due to the characteristics of the packaging, the black gel U disk does not have much advantage in its reading and writing speed. Relatively speaking, the read and write speed of the chip USB flash drive can reach a very high level.

The black colloid USB flash drive, also known as the semi-finished USB flash drive, is the latest technology. Now it is used in batches on the mini series of USB flash drive products.

Due to the high degree of integration, the U disk shells are all the same, and the similarity is large! Chip U disk 1, chip U disk because it is more flexible, so it can control the processing of each part, U disk appearance style novel! 2. The waterproof and shockproof performance is not as good as the black gel USB flash drive, but the chip USB flash drive is better in terms of read and write speed!

1. ** factors.

The more famous the brand is relatively high in terms of **, you can choose according to different budgets, or you want to buy high-quality quality at the lower **, the probability of this happening will be very small!

2. The aesthetics of the appearance of the U disk.

Different brands have different USB flash drive appearances, and the high and practical style is the motivation to buy!

3. What is the read and write speed?

It is an important step to test the read and write speed of a brand's USB flash drive. You can use the USB flash drive test software to test the authenticity, and the faster the read and write speed, the better the quality!

4. Test whether it is an upgrade chip manufacturing.

When the 2GB USB flash drive is forcibly upgraded to 16GB**, it is believed that it will be a deception for consumers.

5. Product after-sales service.

Something that cannot be avoided has happened, but it happens after it is dealt with.

When the brand type of USB flash drive is on the rise, the problem of purchase choice is also realistically placed in front of consumers, it is undeniable that big brands have a strong position in the quality of USB flash drive, one-stop after-sales service team! A finished brand U disk is mainly composed of flash memory chips and USB flash drive shells! No matter what brand of U flash memory chip can not be produced by itself, but imported foreign flash memory chip processing and production!

Therefore, the quality of flash memory chips ultimately determines the quality of the brand USB flash drive!

And the chip U disk can be distinguished from the following three points:

1. The product direction is different.

The black colloid USB flash drive, also known as the semi-finished USB flash drive, is the latest technology. Now it is used in batches on the mini series of USB flash drive products. The chip U disk uses various components to be combined together and has a large volume, which is mostly used for conventional and ordinary U disk products.

2. The shockproof performance of waterproof and closed spring is different.

Since the vinyloid USB flash drive is completely closed, it is resistant to falling in the water, because the water can not damage the working components, and the data will not be lost. The encapsulation layer is made of unique materials, which are fully considered in terms of thermal insulation and pressure resistance and bending resistance. According to the test results, the black gel USB flash drive will not lose data in 100 degrees of water, and can resist the weight of a truck.

The chip U disk uses a combination of various parts, and the parts are exposed, and the waterproof and shockproof performance is not as good as the black gel U disk.

3. The degree of difficulty of recovery is different.

Since the black gel USB flash drive is completely closed, such a package may not be a good thing for data recovery, because it cannot be accessed to the flash memory chip, which causes a certain difficulty to the recovery operation. The chip U disk Peisong uses a variety of parts combination, which is easier than the black gel U disk.

This ** is very clear and I hope you can adopt @

Summary. Dear, you also! About your question:

Why do some black colloid USB flash drives have lines? The answer is as follows: the texture is to prevent copying, and the general vinyl USB flash drive has lines, so that a slight texture can prevent the operation of the replicator, thereby preventing the replication and dissemination of data.

Dear, you also! Regarding your question: "Why do some black colloid USB sticks have lines?"

The answer is as follows: the pattern is to prevent replication, and the general black gel USB flash drive is textured, which can prevent the operation of the replicator with a slight pattern like Qikai, so as to prevent the replication and transmission of data in the state.

At the same time, the black colloid U disk pattern is to increase the appearance and aesthetics of the U disk, so as to make the U disk more textured. This texture and texture also makes the USB flash drive easier to grip, easier to grasp when picked up, and easier to put in your pocket. Moreover, the surface of the black colloid USB flash drive has a certain roughness, and Tangerine Hui can effectively prevent the slippage and bending of the USB flash drive, so as to ensure the safety of the USB flash drive.

Then why most of them don't.

Pro, it may not be the same batch of raw Lu Chan lead production or series. This should not be a quality problem of the U disk, because from the ** point of view, the lines are relatively regular, and they are all in a straight line, and there are also internal storage or other accessories that can be textured as early as possible, which are different from other manuscripts.

If you are worried about the quality of the praise, you can ask the staff or customer service when you buy Yu Yingzi, and make a detailed determination, but I think it should not be a quality problem, and the specific Qingjue pattern application is still what I said above.

Then why are there so few lines made?

Dear, I'm not a business that does U disks, and I do so little about the shape of the lines, this little brother really can't explain it to you, I can only tell you what I have considered, if you still want to ask what lines are so few, why the pattern is like this, I can't explain the pro.

I can only explain for you what I said above, which I don't think is a quality issue, but the specific application usage that I said above.

Obviously, the pattern you gave is very regular, and it is definitely not caused by a collision in quality or transportation.

Generally speaking, the veined USB flash drive has a texture to prevent the USB flash drive from slipping out, which can prevent the USB flash drive from slipping out of the socket, thereby reducing the possibility of damage to the USB flash drive. In addition, the texture can also enhance the appearance of the USB flash drive and provide a better touch. Also, as a cursory observation, I said that it would be more difficult to reproduce piracy.

Maybe not all USB flash drives have this design.

1. The chip of the U disk is generally the main control chip of the U disk, and the black chip is generally detected by the tool software.

2. For example, use chip wizards. After the software is on the Internet, run the exe file, insert the U disk, and it will detect the chip manufacturer and model of the main control. Generally, the products of large manufacturers, such as Qingtai, Phison, Huirong, etc., generally it will not prompt fake, such as Bangxin, Anguo, etc.

3. If there is no prompt when it is confiscated, it is generally of relatively good quality, that is, a white film, and if there is a fake prompt, it is also a black film.

The mass production method of the black gel USB flash drive is the same as that of the ordinary USB flash drive.

1. Use the chip wizard or similar software to find the main control model of the U disk.

2. Find the mass production tool corresponding to the USB flash drive according to the main control model.

3. Insert the USB flash drive into the computer, and run the mass production tool, in the settings of the mass production tool, check the CDROM item or change to the dual-partition function mode, and then mass produce the U disk.

Different mass production tools have different setting methods, the following is the mass production setting of Hui Wing main control U disk as an example (there are more U disks of vinyl Hui Wing main control), you only need to check "make auto run" and then select the ISO file used in mass production, and then save the settings and mass production:

The same mass production method, first use chipgenius to check the main control model, and then find the corresponding mass production program mass production, vinyl and ordinary U disk are different, if it is killed, the pins of the main control can not be shorted to resurrect, but some vinyl has contacts on it, and it can also be operated.

This kind of U disk can not be disassembled, you might as well find a dealer, see if you can warrant, paid warranty is also worth it, it seems that this King of Biao's U disk should add a lot of money.
