So it seems to work AND to be reliable. I would leave it enabled, if I were you. Lou Lou 31 1 1 bronze badge. Sign up or log in Sign up using Google.

Featured on Meta. Custom Filters release announcement. Linked 0. TRIM allows the operating system to actively inform an SSD which blocks of data are no longer in use and can be wiped internally. This helps the drive work more efficiently and leads to faster performance and most importantly, longer lifespan.
You can read more about that here. If the value is No, then you need to turn it on. The system will display a notice, then ask you if you are sure you wish to proceed.
Type in y and then press enter. The system will then indicate that it will reboot and ask you if that's OK.
It should not be used in a commercial operating environment or with important data. Before using this tool, you should back up all of your data and regularly back up data while TRIM is enabled. Enabling TRIM by using the trimforce command requires the Mac to reboot, which will happen automatically once the feature is enabled or disabled. If you want to turn off the TRIM feature within OS X on this party volumes, you simply need to change the trimforce command to disable instead:.
Enjoy this tip?
Ever since Apple first offered Macs with SSDs, they've included support for TRIM, a method for the OS to assist an SSD in freeing up space. I also have a Samsung SSD, but mine is the GB size. enable TRIM, first save all your open documents as this will reboot your Mac.

Please help me. Take care of keeping your working version of the tool Trim Enabler if you have one, and do not update it since now it is no longer free but must be paid if updated to the current version. You only learn of the new payment need once you made the mistake of following the suggestion of updating it….
Early on, I turned Trim Support off for several months and my machine slowed in performance in a huge way. I have had no issues at all with this setup.
If you overwrote your OS when you installed El Capitan, you may have to re-enable trim on your new system. Thank you for your reply.
Strange as I did update the software through the App Store. When there is no trim support, it just does not do anything like on a HDD , if it is supported the SSD controller will use it.
Do not use trim. And certainly not on the blacklisted SSDs, see my post above. It has a Fusion Drive. And, also is it effective with an external SSD?
If your drive is not a 3rd party drive, you do not need to enable TRIM. Apple enables it on all of their provided SSD volumes by default. Verify it using System Information.
Second question: yes, external drives will also be trimmed, if they are using AHCI, i. This works, though be aware that many such drives perform poorly with TRIM. Test it out before depending on it. Click on the applelogo, left upper corner, click on info, click on system, click on sata and then watch the right window. And there is shows if it is on or of. No, it actually does indicate if it is on or off.
How can I check whether trimforce is enabled or disabled. I believe that in El Capitan Trim is enabled automatically so you do not need a special tool anymore.
Not all drives are meant to have TRIM enabled. In fact, Samsung specifically warns not to enable trim on their SSDs. There is simply no need, and in fact can result in a loss of useable space and lowered performance. For the best information on SSDs, head to anandtech.
