Trim

TRIM is an interface command that marks data on an SSD as eligible for deletion. With TRIM turned on, the SSD will delete this flagged data when the computer is idle. This frees up space on the SSD and speeds up the process of writing new data.

The TRIM command allows the operating system to know exactly in which block the data to be written or deleted is on the SSD. Thus, when a delete command is given to a file, the TRIM command instantly clears the block or page where the files are stored. Thus, when data is to be written to that field, the system does not wait and slowness does not occur.

Advantages of Turning on TRIM

The advantage of TRIM is that it increases the operating speed of the SSD. It also extends the life of the solid state drive by reducing wear.

Disadvantages of Turning on TRIM

The biggest downside is that recovery programs won't work if you want to restore deleted files once you've issued the TRIM command.

TRIM can also corrupt some SSD models (blacklisted) with faulty drive firmware. So check if your SSD model supports TRIM before enabling it. Otherwise it can be risky.

Steps to follow when enabling TRIM:

  • Find out if your SSD model is blacklisted
  • See if your operating system supports TRIM
  • Check if TRIM is turned on
  • Activate TRIM
