Trim and OS X® operating systems
A common question customers ask is "should I enable Trim on my Mac®"? Depending on your OS revision, doing this requires a 3rd-party program, or entering some terminal commands. Crucial® SSDs also have a built-in feature called garbage collection. For more information about Trim and garbage collection, see the following link:
Trim and SSD Performance: Why is it Important?
This video shows a benchmark first with Trim enabled, then with Trim disabled. You will see small fluctuations in speed in both cases, but these fluctuations would not be noticeable under normal use.
As of OS X version 10.10.4, the trimforce command is available in Terminal to enable Trim without the use of third-party software. According to Apple®, enabling Trim using the trimforce terminal command is done completely at the user’s risk. If you decide to enable Trim using the trimforce terminal command, it is suggested you back up your data first. We have had users report that activating Trim using the trimforce command increases system boot times by about 10 seconds, though speeds during all other system use appears to be as fast as without Trim. Please refer to support for your OS for details on using Terminal to enable trimforce.
While Trim is generally good for helping to manage SSD performance and wear in most desktop and notebook environments, it is important to note that Trim is not critical and the improvement may only be marginal. The internal garbage collection algorithms on Crucial SSDs manage deleted data quite effectively. The question of enabling Trim really has to be answered by the user. If you are a casual user sho uses your system for Internet, email, and other light tasks, garbage collection built into the firmware of Crucial SSDs will probably be plenty to keep your SSD running fast and healthily. If you are more of a power user who does picture and video editing or other tasks that require a lot of writes, enabling Trim might be more useful to you, because constantly writing workloads do not always allow for regular maintenance from garbage collection. We hope this information helps you decide what is best for you.
