1. SSD reads and writes faster. SSD and USB flash chips have the basis for faster read and write speeds, but to determine the final read and write speeds and speed stability, the performance of the master chip and algorithms are needed. SSD's master control is much more complex than the u-disk, and it will be optimized for the SATA or M.2 interfaces so that it will reflect the use of the
2. SSDs have a longer lifespan, and the lifespan of a flash memory chip is considered in terms of the number of times it can be read and written to. Because the larger the capacity of the SSD, the more flash chips are needed, the master chip can be allocated according to the size of the file, which improves the speed and extends the life of the flash memory.
3. SSDs can read and write synchronously. Thanks to the algorithm of the master chip, SSD can realize synchronous reading and writing at the same time, while the u-disk can only read and write at the same time, so the reading and writing speed is not as fast as SSD;
