    First, the life span is different.

    U disk failures frequently occur because the general U disk is generally a FLASH chip. Two more chips will accelerate the same storage structure unit on a chip repeatedly. The aging of the chip, and the chip on the solid state drive is far more than one, two, but up to dozens of chips. Through the coordination of the master control, the data is allocated to different chips for operation, and the usage of each chip is balanced. Superimposing the read and write times of all chips greatly prolongs the stable working time.

    Second, the main control algorithm is different

    The solid state drive uses a special algorithm, which is different for each manufacturer, and it is packaged in the main control chip of. Through this algorithm, the data can be evenly distributed to each flash in the solid state drive, which greatly extends the life of the flash while improving the speed. More efficient algorithms can compress and read data at a high speed, especially the read speed can be very high. A more efficient algorithm may be flat, but it can greatly extend the life of the FALSH chip. Generally, the solid state drive can be used normally. Questions and answers in 3-5 years are not big.

    Third, you can read and write at the same time

    I don’t need to say more about this. If you don’t believe me, try it. At the same time copy a file from the hard disk to the U disk and copy a file from the U disk to The speed on the hard disk is much slower than when you copy files to the U disk or hard disk alone, because the same storage unit structure of the FLASH chip can only perform a single operation of reading or writing at the same time. FLASH reads and writes data by voltage changes. One voltage is required for reading and one voltage for writing. It is impossible to generate two voltages at the same time, but if there are many chips and the data is scattered, then for a combination of chips It is said that simultaneous reading and writing is possible.

    The speed is different, the storage is different, and the lifespan is different

    It’s easy to make it clear that the USB flash drive is a flash memory There is no cache chip There is no master control The basic use is polishing The card reader is the principle of the USB flash drive.

    Solid state has a cache. There is a master control. The cache is a stable transmission speed. The master control is responsible for adjusting the transmission speed with the cache. The fastest USB flash drive is 100M per second. A better solid state Up to 5000M per second

    The difference is very big, U disk is convenient to carry, but it is easy to break, solid state hard disk is stable and not easy to break but it is inconvenient to carry

Through the coordination of the master control, the data is allocated to different chips for operation, balancing the usage of each chip, and virtually superimposing the reading of all chips. The write times greatly extend the time of stable work.
