In Windows 7 and newer operating systems, the TRIM command can be used to maximize the life and performance of Solid State Drives (SSDs). Using this command is known as trimming the SSDs. This command is useful as SSDs operate differently (internally) from HDDs (Hard Disk Drives). The TRIM command will notify the SSD on which blocks no longer contain data that needs to be persisted, and a few low level operations later, the data on these blocks can be safely deleted.
In windows, to see if you have trimming enabled, run the following command on the command line:
fsutil behavior query DisableDeleteNotify
If the result is a 0, it means that TRIM is enabled. A 1 indicates that TRIM is not enabled. To enable trimming, run the command below:
fsutil behavior set DisableDeleteNotify 0
