    Hey everyone,

    So my mid-2012 MBA was suddenly crashing constantly a few weeks ago, and eventually stopped booting, which I eventually determined was the factory 128GB SSD having cooked itself. I ended up replacing it with a 240GB SSD, the JetDrive 520 from Transcend. I've been doing some research on TRIM support (I'm running El Capitan currently) since I installed the new SSD and got everything back up and running.

    It appears I can enable it through the terminal, which seems to be the common solution, but Transcend also offers this "JetDrive Toolbox" as a free download which apparently acts as an SSD monitor as well as a few other functions, including enabling TRIM on the drive.

    Two questions - First of all, I've read a few people had experienced instability issues when enabling TRIM under Yosemite, but can't find issues under El Capitan, so I'm wondering if anyone would be able to offer any reasons/arguments AGAINST enabling TRIM, as it's currently disabled?

    Secondly, if I were to enable TRIM, would there be any argument to use the JetDrive Toolbox instead of the terminal command "trimforce enable"?

    Thanks in advance!

    Use TRIM. Enable it any way you choose. One is not preferable over the other. They both perform the same function.

    Any particular reason why it's not enabled by default? It just seems odd to me.

    Thanks for the quick reply Lou!

    As above. Enable TRIM, however, I would go with the JetDrive Toolbox as that is designed specifically for your SSD. Enabling TRIM via the Terminal has been problematic for some users so I would avoid doing it that way. As for why it's not enabled by default, I suspect the manufacturer is being cautious in that they do not know how and where their SSD will be used.

    It's not enabled by default, because the OS doesn't recognize it as an Apple drive. Only Apple drives will enable TRIM by default. I know of no issues enabling TRIM using the terminal.
