For example, in a Windows environment, when an SSD reports that it has TRIM support, the OS will disable disk defragmentation and enable TRIM.

In order for TRIM to function, the host's OS and the SSD must support it. NAND flash wears out due to the long-term effects of the P/E cycle, so reducing the number of erases can lengthen the endurance of the SSD. The SSD then has fewer pages to move during garbage collection, which reduces the total number of program/erase cycles ( P/E cycles) to the NAND flash media and prolongs the life of the SSD. The SSD TRIM command simply marks the invalid data and tells the SSD to ignore it during the garbage collection process. TRIM eliminates any unnecessary copying of discarded or invalid data pages during the garbage collection process to save time and improve SSD performance. The TRIM command enables the operating system (OS) to preemptively notify the SSD which data pages in a particular block can be erased, allowing the SSD's controller to more efficiently manage the storage space available for data. SSD TRIM is complementary to garbage collection. Garbage collection may wait for lulls in drive activity to initiate the process, sometimes leaving pages that are obsolete in the SSD. When a previously written block is targeted for garbage collection, the valid data pages are gathered up and moved to another block on the SSD so that the block containing the old, invalid data pages can be erased.

Garbage collection manages and maintains the available storage space, handling the disparity between the erase unit size (block) and the read/write unit size (page). An internal SSD housekeeping operation known as garbage collection helps to streamline the process. But, before any data can be written or programmed to the SSD, an entire block of data that is no longer needed must be erased. NAND flash-based SSDs read and write data in units known as pages, and in a typical SSD, 128 pages constitute a single data block. The T13 Technical Committee of the International Committee for Information Technology Standards (INCITS) has incorporated the TRIM command into the ATA standard. The DEALLOCATE operation provides a similar capability in the nonvolatile memory express ( NVMe) command set for Peripheral Component Interconnect Express SSDs.

UNMAP is the comparable Small Computer System Interface ( SCSI) command for use with SAS SSDs.

TRIM, which is not an acronym, is available for SSDs that support the Serial ATA ( SATA) interface. The use of TRIM can improve the performance of writing data to SSDs and contribute to longer SSD life. 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.
