Mac OS X 10.10.4 Finally Adds TRIM Support For 3rd Party SSDs
Now that the latest version of OS X 10.10.4 has been released, let us get to the most exciting feature of all; TRIM support. Previously, Apple only provided TRIM support to SSDs that were already present in the company’s MacBook lineup of products but now, the company has extended that support to third party solid state drives. After all, purchasing better SSDs for increased performance gains is a very resourceful approach and with OS X 10.10.4, users will finally be able to rejoice.
OS X 10.10.4 TRIM Support Can Be Enabled By A Single Command-Line Executable
One of the major differences separating OS X and Windows was TRIM support for aftermarket SSDs. It appears that Apple has finally grown a big heart. For those who are unaware of what TRIM does, Extreme Tech TRIM is a garbage collection method that allows the OS to tell the SSD which blocks of data are no longer in use and can be deleted.
SSDs also perform their own internal garbage collection, but the TRIM command in operating systems helps to increase the overall lifespan of these drives by avoiding write amplification. This is done by not re-writing data that’s actually been cleared for deletion. Through this approach, SSDs are able to maintain their lifespan and provide tremendous read and write performance over an elongated period of time.
Now let us come to main part; in order to enable TRIM on OS X 10.10.4, a simple command-line executable called ‘trimforce’ is going to have to be entered. As you can tell from the image, after the command has been executed, you will be met with a series of text, which is nothing out of the ordinary. However, those who plan on purchasing Samsung or Crucial SSDs will have to be very careful when making that purchase because ‘trimforce’ will not be supported on all SSDs.
Instead, the website reports that enabling this command on the aforementioned lineup of SSDs will have detrimental effects on their overall performance, and might even lead to data corruption. According to the data accumulated by a search API company called Algolia, significant problems have risen due to enabling this command.
Samsung had earlier refused to diagnose or examine the problem, because of two reasons:
- It’s only an issue occurring in Linux.
- The company prioritizes drive support for Windows, which is a no-brainer seeing as how Windows leads from the front in the desktop operating system market share.
Samsung is currently investigating these issues, but we advise you guys to pick up something that has not been stamped with a Crucial or Samsung logo.
Now that this has all been cleared up, it is time that you took on an SSD hunt mission and snared yourself a blazing fast storage drive, because TRIM support enabling only takes a mere seconds to execute.
