TRIM is a service that runs in your operating system and works with SSD hardware to track what blocks on the drive are unused, and then prepares them for writing. When put in use, TRIM can optimize SSD performance, especially on drives that are relatively full or used for storing and deleting large amounts of data.

While rare, you might experience a problem in OS X where the Finder will not display the contents of specific folders.
