The main purpose of the TRIM command is to reclaim unused space on thin-provisioned storage. It helps by actually deleting the free'd pages when a file is deleted, thus ensuring that when we come to perform a write there are actually empty pages available.
This avoids the read, modify/erase, write cycle at the time when we need a low latency write to complete.
