The purpose of TRIM is to tell the drive that some # of sectors are no longer important so that it doesn't have to work as hard in its internal garbage collection.
The sector size does not typically match the FLASH page size so the SSD still has to do some heavy lifting. It has to keep track of many small "holes" in the FLASH pages. This seems pretty complicated since all of this information needs to be well-preserved in non-volatile storage.
