On Tuesday, Apple released the latest update to OS X with version 10.10.4, which among other improvements adds the support of TRIM for third-party SSDs.
The new “Trimforce” command can be executed from the OS X terminal and allows users to enable TRIM on their SSDs without having to download and install anything or resort to software “hacks”.
While OWC SSDs are built to perform at optimal levels with or without TRIM enabled, you may still wonder whether you need to utilize the Trimforce tool for your SSD.
A little TRIM background
On SSDs, performance can slow down over time if the drive runs out of “empty” space where it can write data. To help with this, SSDs have a process called “garbage collection” that rearranges data and clears out unused space while the SSD is idle. TRIM helps garbage collection by telling the SSD which areas contain deleted data so that data doesn’t need to be moved.
Microsoft Windows began native support of the TRIM command for SSDs in Windows 7, and Apple added support in 10.6.8. But until 10.10.4, Apple has supported TRIM only with original Mac SSDs.
What does this news mean for your OWC SSD?
Through the DuraWrite technology, over-provisioning, and garbage collection, OWC SSDs have been built to continue running at optimal speed and provide peak performance throughout their lives without TRIM.
However, this doesn’t mean you can’t enable TRIM. Our testing has shown no issues with using Trimforce or third-party enablers with an OWC SSD*.
If you do decide to enable TRIM using an OWC SSD, to avoid any possible issues it is important to make sure that the firmware has been updated. The current generation of our SSDs need at least version 5.06 and the previous generation SSDs require version 3.65. If you aren’t running the latest version, OWC makes updating your firmware easy, and it can be found for your first or second generation OWC SSD here. As always, OWC is committed above all others to supporting the Mac platform with these continued update capabilities for Mac users.
And while you will enjoy optimal performance levels from your OWC SSD with or without TRIM active, we do applaud Apple’s decision to allow for TRIM with non-Apple SSDs. It’s an exciting development many in the SSD, Apple, and OWC community have been interested in seeing come to light.
