— module support for TRIM command.Feature of the operation of SSD modules is that when deleting data in the normal mode (without using TRIM), changes are made only to the “table of contents” of the drive: certain cells are marked as empty and ready for new information to be written. However, the old information is not deleted from them, and when writing new data, you actually have to overwrite it — this significantly slows down the speed of work. The TRIM command is designed to correct the situation: when it arrives, the drive controller checks if the cells marked as empty are empty and cleans them if necessary.
Of course, this function must be supported not only by the drive, but also by the system, however, the ability to work with TRIM is built into most popular modern operating systems.
