first, the main control algorithm is not the same SSD is a special algorithm, this algorithm is different from each manufacturer, and is encapsulated in the main control chip. With this algorithm, the data can be distributed evenly to each flash on the SSD, while the speed is increased, the life of the flash is greatly prolonged. More efficient algorithms can be high speed data compression read and write, especially the reading speed can be achieved very high, more efficient algorithm may be f
