Selected Answer: A

What is TRIM TRIM is the function that allows you to improve the long-lasting performance of SSDs by better managing the various reads and writes of the cells, so you will not only increase the life of the SSD but also speed up the read and write operations. SSD TRIM is an Advanced Technology Attachment (ATA) command that enables an operating system to inform a NAND flash solid-state drive (SSD) which data blocks it can erase because they are no longer in use. The use of TRIM can improve the performance of writing data to SSDs and contribute to longer SSD life
