Crucial SSDs and TRIM/Garbage Collection
Since not all operating systems support TRIM, Crucial SSDs have a special feature called Active Garbage Collection. Active Garbage Collection is a process that helps an SSD maintain optimal performance by freeing up memory sectors that are no longer in use. Garbage collection is part of the SSD itself and thus not dependent on your computer’s operating system. Since garbage collection is part of the SSD’s firmware, it works regardless of which operating and filing systems your computer is using.
Note: Garbage collection only works when your Crucial SSD is idle, so make sure to configure your system so it doesn’t go to sleep when it’s idling. Garbage Collection takes time to do its job, but as long as it gets time to idle every now and then, your Crucial SSD will maintain its high level of performance over time.
