    Q:What is the TRIM command?

    A:   The TRIM command allows the OS to acknowledge the SSD controller the locations of unwanted pages proactively, saving operating time in the next write operation. NAND flash only writes data at the block level. When TRIM is active, and there is data to be erased or written, the SSD manages to write data into blank blocks with efficiency. TRIM is only active when both the operating system and the flash controller both support and enable this function.
