Is there a big difference between the number of times used by miscellaneous USB flash drives and bra

There is a limit to the number of times, but the number exceeds the limit of daily use.

To tell the truth, it's best not to buy miscellaneous cards, and most of the miscellaneous cards use some garbage main control + black films. Not to mention the slow speed, if it breaks one day, it will really want to cry without tears.

Strong hands-on ability to install one, can be stronger than the brand, I originally made one, the writing speed is 30m s (Samsung dual channel).

The gap is big, but the miscellaneous U disk can also be used more than 20,000 times, you read and write once a day for 7 or 8 years, at that time I don't know how big the U disk to use, buy miscellaneous cards!!

Yes, the quality of miscellaneous USB flash drives is difficult to guarantee.

U disk chips are graded, and there are A-grade, white, black, etc. There is a core component in the structure of the chip called the wafer. The grade of the USB flash drive chip is divided according to the capacity of the wafer.

1.The capacity of A-level chips is generally higher than 93%, and most of them are packaged by factories, which we usually call original chips or A-quality chips. Most of these chips are used on well-known brand flash drives, and they usually come with a warranty.

2.Wafers with less than 93% capacity are called downgrade flashes, which are no longer marked by the original factory and are processed by some small packaging fabs. Among them, the relatively sufficient amount and the use of stable are generally called white tablets. **Generally 7 to 8 percent of A-grade products.

3.Black chip: The chip to be packaged is seriously insufficient in capacity and difficult to guarantee the quality of the black chip. In addition, some unscrupulous businesses ** flash memory chips polished from waste flash memory chips are generally called black chips.

Therefore, it is recommended to buy a brand USB flash drive through regular channels.

It should be a small difference, about 20,000 times.

It's hard to say. It depends on the JS conscience of miscellaneous cards =,= Actually, now the big brand of the U disk is not very expensive, why consider miscellaneous cards?

The main difference between genuine and miscellaneous is warranty and stability.

Miscellaneous cards (can also be said to be copycats. Even if you use it one day, you lose data.

Genuine cards are generally not, unless luck is too embarrassing. =ω=

U disk brand recommendation:

1. Patriots

AIGOSTAR brand products have always been known for their excellent value for money. Patriot USB flash drive products are no exception. The ** of the Patriot USB flash drive is relatively low, but this is only relative to the ** of other brand products. The quality of its USB flash drive is no worse than the latter.

2. Samsung

Samsung is a well-known electronic brand in South Korea, and Samsung USB flash drive is the aristocracy in the USB flash drive. Although the ** of Samsung USB flash drive is slightly higher, its USB flash drive is generally designed with security encryption function, and Samsung USB flash drive does a better job of privacy protection in data transmission.

3. Toshiba

Toshiba brand USB flash drive products are divided into two types, one is an ordinary small-capacity USB flash drive, and the other is a large-capacity USB flash drive with a separate chip. Toshiba USB flash drive has a better encryption design for the storage of ** resource data in MP4, MKV, RMVB and other formats.

4. Taipower

Taipower is an electronics brand from Taiwan. The storage rate of the Taipower USB flash drive can generally reach 500 megabytes of output and 300 megabytes of second write. In general, Taipower USB flash drives are compatible with many types of systems.

Taipower USB flash drive is also one of the few USB flash drives that are compatible with Win XP systems.

5. Kingston

Kingston is a world-renowned brand of storage products. It is not only well-known in USB flash drive products, but also has achieved remarkable results in computer hard disks. Kingston USB flash drives are basically designed with a metal case. Its USB flash drive is relatively sturdy and durable.

The U disk on the market is uneven, and you can distinguish the good from the bad in the following ways:

1) Look**. **The price of the USB flash drive is obviously higher than the price of the parallel USB flash drive.

2) Speed measurement. The read and write speed of a good USB flash drive is fast, and the general write speed of the USB flash drive can reach 8--10MB s, and the read speed can reach 15--20MB s.

3) Look at the packaging. The good U disk is finely worked, including the packaging, which is not casual.

4) Use the tool of the USB flash drive to detect. For example, the "U disk expansion detection tool" of Digital Home can detect the quality of the U disk.

It's good that the USB flash drive can be used! If it can't be used, it is divided into two types: the first is plugged in the computer dealer and there is no response, and it is broken; The second is to plug in the computer and have a response, you can find the mobile hard disk, but you can't open the prompt, please insert the G disk, which can be repaired with mass production tools!

Choose the big brands such as USB drive, Kingston, SanDisk, Apacer, and Baike, and go to the specialty store, or buy it with authorization!

The main thing is the speed of reading and writing, there is no problem with the speed of general reading, the difference in writing speed is relatively large, the most general is 5Mbit S, the good one can reach 20--30Mbit S, ** it is relatively high, and the ordinary U disk that can generally reach 10Mbit S is very good!! Capacity secondly, when the USB flash drive itself is mass-produced, you can choose capacity priority or speed priority, the capacity priority speed is slower, and the capacity loss of speed priority is larger!!

How to identify whether the USB flash drive is expanded, teach you a way to quickly identify the quality of the USB flash drive, simple and practical.

1.Capacity problem, after all, the U disk is not as big as the mobile hard disk, the real mobile hard disk is generally more than 10-40+G, and the relative capacity of the U disk is small, but there are also large-capacity mobile hard disks called U disk;

The disk in some systems, me, etc.) can not be identified by itself, and the driver must be installed to identify it.

If the USB flash drive fails, the data inside is "inevitable", even if you spend a lot of money to do data recovery, then they can't do anything. Because the USB flash drive uses a flash memory chip, once it fails, it will not be able to remove the disk for data recovery like a hard disk.

This is the fatal flaw of the USB flash drive.

USB flash drive is susceptible to virus infection? Could it be that the portable hard drive will not be infected? As long as you take precautions and don't let this type of autorun run automatically, you'll be fine.

It is easy to be infected by viruses and is highly transmissible.

The brand should be a little better, at least there is a warranty, there are many problems with many cottages, buy a U disk and pay attention to the following:

1.To choose a metal case.

Although the quality of some USB flash drives is quite passable, the shell is very thin and it will be broken accidentally. All that's left is the central data board. This USB flash drive is wasted. Although the metal USB flash drive is more expensive, it is durable.

2.Pay attention to buying brands.

The brand's USB flash drive is guaranteed, and the USB flash drive itself is easy to break. If you buy those bad USB flash drives, it is more likely to be bad. But the brand U disk is always relatively good, and the after-sales service is also very good.

3.Pay attention to anti-counterfeiting.

When buying a USB flash drive, you must pay attention to buying a brand. In fact, no one can see which one is the first and which is a forgery, and there is an anti-counterfeiting mark. Different brands of USB flash drives have their own screening methods, and you can check them on the official website.

4.Read/write speed is to be considered.

What should I pay attention to when buying a USB flash drive, and what should I pay attention to when buying a USB flash drive. The read and write speed of the USB flash drive is very important, especially for those who need to store large-capacity data back and forth, for a best brand in China, the read and write speed is relatively average. Some USB flash drive manufacturers focus on read and write speed.

5.Pay attention to whether the interface is or not.

Many USB flash drive users do not pay attention to the interface problem, resulting in slow read and write speed. In fact, it is much faster, but ** is also relatively high, and the average person can actually use it. Not for work use, no need to buy such a good one.

6.It depends on the actual amount of storage.

Basically, there is only 8G of USB flash drive memory, that's for sure. Therefore, when buying a USB flash drive, you must not buy it with the maximum capacity. Otherwise, you won't be able to save it after you buy it. If you're not sure, buy a bigger one.

It is necessary. Because you may have important data stored in it. Be sure to ***. I can't resist the blow of the virus. It's useless if you sell it.

USB disks are all about the same, as long as you pay attention to it when you use it, it won't break.

I've bought cheap ones before, but they broke down after a few uses, and then I used them all right.

One hundred and dozens of dollars, a famous brand bird

Just go to the street and buy one

Compare safe and reliable points. There is a quality guarantee.

Just buy Kingston's. 4G for 80 pieces.

It's not necessary, but buy brand K gas.

will affect. After the exchange of data is completed, the USB flash drive should be taken off immediately, do not use the USB flash drive as a hard disk, and try not to open the USB flash drive for a long time, read the data in the USB flash drive, and do not plug it into the computer for a long time. This is because:

1. U disk is used to temporarily store and exchange data in land, in terms of design, it is not like a hard disk installed in the host for a long time to open and use, U disk has no heat dissipation measures, plugged into the computer will produce greater heat, the longer the time, the higher the heat, the light will shorten its service life, and the remake will be burned.

2. In addition to the power consumption, the U disk plugged into the computer also occupies system resources and affects the running speed.

3. Plugged into the computer is easy to be attacked by Trojan viruses, and it is easy to lose files in the USB flash drive when using the dormant server.

4. Plug in the computer to switch on and off to detect it, resulting in slow on/off, and sometimes there will be problems of not being able to turn on and off.
