Bringing Trim to Mac OSX


Trim Enabler is the first and safest utility for enabling Trim in Mac OS X. With the flip of a switch you can improve the speed and longevity of your Solid State Drive.

What is Trim?

Every time you delete a file on your computer, the data still stays on the drive in segments called blocks. These blocks are not deleted until you need to use them again to write new data. Due to technical limitations in the NAND Flash design, only whole blocks can be deleted. This means that when you need to write new data, the SSD must perform time-consuming cleaning and maintenance of these blocks before your data is written. With Trim, your blocks can be cleaned instantly when you delete the data, leading to much less operations during the writing process which gives you better speeds and minimizes the wear on the drive.


Is my SSD supported?

Any SSD (internal or external) with Trim support should work with Trim Enabler. Please make sure your drive has the necessary firmware version in order to support Trim.

Does Trim work with Fusion Drive?

Yes, it works fine!

What about RAID?

Trim in RAID depends on the RAID drivers. If you are using OSX software RAID 0 then it should work fine, but hardware RAID generally does not support Trim.

My SSD has Garbage Collection (GC), do I need Trim?

GC and Trim are not the same thing. As a matter of fact, they work well together. The SSD Review did a great article describing the benefits of using both features together.
