If the main control of the USB flash drive is broken, the card must be reopened. Different manufacturers have different main control chip models. You need to download the official mass production tool, so that the data stored in the USB flash drive will be erased. Shenzhen USB flash drive factory brand products can go to the after-sales service, first check the pins and excuses, and troubleshoot contact problems, hoping to recover.
Data that is not particularly important can be formatted to see if it can be opened. If it can be opened, use the data recovery software to retrieve it. It seems that the price drop of flash memory caused the general price drop of USB flash drives. But what I don’t understand is why I think that the well-known manufacturers of Toshiba will also do some opportunistic things (conceal the problem of the consumer USB chip model), but when I checked the product consultation, I found a more incomprehensible problem . Consumers asked whether the flash memory chip is the main control of MLC, and the merchant would answer that because the products are of different batches, they are not sure whether the chip is MLC or TLC. Please refer to the specific product. My TMD is very speechless, do I expect my character to explode when I get a USB flash drive? ? ? Offer SLC MLC TLC difference SLC=Single-LevelCell, namely 1bit/cell, fast speed, long life, super expensive (about 3 times the price of MLC), about 100,000 erasing life MLC=Multi-LevelCell, which is 2bit/ Cell, the speed is generally average, the life is average, the price is average, about 3000—10000 erases and writes life TLC=Trinary-LevelCell, that is, 3bit/cell, there are also Flash manufacturers called 8LC, slow speed, short life, low price, about 500 erases and writes Life span, currently no manufacturer can achieve 1000 times. As can be seen from the above little knowledge, SLC has the best performance and super high price. Generally used as enterprise-level or high-end enthusiasts. MLC can be used. The moderate price of the Shenzhen USB flash drive is the mainstream of consumer SSD applications. Most mainstream brand products such as Intel, OCZ, Kingston, Micron, etc. are MLC. TLC has the lowest comprehensive performance and the cheapest price.
