The Trim Enabler Pro Version allows you to activate the full version on up to 5 computers, it has the solid state drive performance enhancing features and other locked features.įor older version 10.6.8? Download Trim Enabler 2.2 here Guide to enabling Trim in OS X Yosemite Developer Preview 1 using Trim Enabler
If you are using OSX software RAID 0 you are fine, most softwares are supported. For hardware RAID they do not support trim, therefore it does not work with it, however trim in RAID depends on RAID drivers. Trim Enabler works well on Fusion Drive, and most SSD. The detailed S.M.A.R.T monitor will provide performance and health relevant statistics and reports about your disks, both Hard and Solid State Drives Trim decongest the SSD by releasing blocks of data that are no longer in use.
It is allows you to free up enough space on your SSD, you can access advanced OS X tweaks to improve your SSD’s performance or free up to several gigabytes of disk space. The performance of the solid state drive is enhanced by making it writer faster, the increase in writing speed is also coupled with a long-lasting performance and lifespan. 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. 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.
Due to technical limitations in the NAND Flash design, only whole blocks can be deleted. These blocks are not deleted until you need to use them again to write new data. I experienced this firsthand when my SanDisk SSD started slowing down as it got older before enabling TRIM on it.Every time you delete a file on your computer, the data still stays on the drive in segments called blocks. Once your computer restarts, check System Report again to see if TRIM Support changed to Yes.įinally, TRIM does matter, even for modern SSDs with sophisticated garbage collection. Just open Terminal and type “sudo trimforce enable”.
If it is listed but says “No”, you can try turning TRIM on by using the trimforce command in terminal. If TRIM Support is not listed, your enclosure most likely does not support TRIM.
In order to check if your enclosure supports TRIM, you’ll want to go to Apple > About This Mac > System Report > Hardware > SATA/SATA Express > and look for “TRIM Support” under the enclosure specs. I used the trimforce command in terminal to enable it. Most Thunderbolt enclosures should support TRIM, and I currently have TRIM enabled on a SanDisk Extreme SSD in an Akitio Thunderbolt 2 enclosure. Firewire supposedly supports TRIM, but I haven't tested it. All five of the USB 3 enclosures / docks I have support it. The vast majority of USB enclosures do not support TRIM, but allegedly there are some that support it such as the JMS 578 USB bridge controller (source: ). (I have sources but Stack Exchange won't let me post more than 2 links)Ĭontrary to many of the comments here, the interface DOES matter. Then in OS X 10.10.4, Apple introduced a “trimforce” command which enabled TRIM on 3rd party SSDs without turning off kext signing.
Later, OS X 10.10 (Yosemite) introduced a security requirement called kext signing which prevented TRIM Enabler from working without completely turning off kext signing. To get around that restriction, software such as Cindori's TRIM Enabler allowed TRIM to be used on 3rd party SSDs. I realize this question is over 4 years old, but I'm adding a comment because this page was the first hit for a Google search on the subject and some of the comments are outdated whereas others were plain wrong.Īpple added native TRIM support in OS X 10.6.8 but only for Apple OEM SSDs.
