Enable Trim Support

TRIM for Solid State Drives is in Mac computers only enabled for original parts. If you replaced your SSD with an aftermarket SSD, your Mac won’t use TRIM with it.

It will tell you so in the main screen of Disk Aid Pro:

What is TRIM anyway, and why should I enable it?

TRIM makes the operating system send a signal to your SSD every time you delete a file, making the SSD delete this file (instead of marking it “deleted”). Writing to empty flash is faster, since the data don’t need to be erased before writing. The SSD will become slower and slower over time if deleted files are not removed from the SSD.
