![]() Trim also affects the longevity of the solid state drive. This takes slightly more time to do than just writing the new information, so using Trim and Active Garbage Collection helps your SSD perform write commands more quickly. The drive would need to erase the existing information, then write the new information. If the Trim command did not exist (as was the case before Windows® 7), then the solid state drive would not know that certain sectors in the drive contained invalid information until the computer told the drive to write new information to that location. The next time the computer is idle, Active Garbage Collection will delete the data. The Trim command tells the drive that the data can be removed. Instead, the area of the SSD that contains the data is marked as no longer used. Because of the way solid state drives read and write information, the data is not deleted from the drive at the user's command. From the user's perspective, this data has been deleted from a document. The Trim command tells the SSD that specific areas contain data that is no longer in use.
