DRAM buffer

— buffer memory is a small chip on an SSD drive that acts as a data transit between the drive and the motherboard. In fact, it acts as a kind of intermediate link between the computer's RAM and the drive's own permanent memory. The buffer is used to store the most frequently requested data from the module, which reduces the access time to them - the information is sent from the cache, instead of being read from the magnetic media. As a rule, the larger the buffer size, the higher the speed of the drive, all other things being equal. Also, drives with a large amount of buffer memory reduce the load on the processor.
