![]() I experienced this firsthand when my SanDisk SSD started slowing down as it got older before enabling TRIM on it. ![]() 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: ). Hy Ihave in my laptop an SSD drive,so Iknow the TRIM have to be enabled,so icheck inCMD (ADMIN) and type: C:\Windows\System32> fsutil behavior query disabledeletenotiey then click enter.after enter. (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. Is Trim Enabled Checking a few things I ran the command to check if Trim is enabled and got this: C:WINDOWSsystem32>fsutil behavior query DisableDeleteNotify NTFS DisableDeleteNotify 0 (Disabled) ReFS DisableDeleteNotify 0 (Disabled) I thought if it showed 0 it meant its enabled. 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adding a comment because this page was the first hit for a Google search on the subject and some of the comments are outdated whereas others were plain wrong.Īpple added native TRIM support in OS X 10.6.8 but only for Apple OEM SSDs.
