Do I need to turn TRIM support ON?

Hi, den.ted!

Thanks a lot for a reply.

Here is the formal manufacturer answer:

But the question remain – do anyone have tried to turn TRIM support ON for this SSD?:

Let me know, please, what is the result?

Thanks.

It's very unlikely a manufacturer will make a specific recommendation regarding TRIM. As for myself, if the solid-state drive is less than three years old I turn on TRIM.

Thank you for reply.

However, before you make this change make sure your Time Machine back up is current and I would do a clone of the hard drive using Carbon Copy Cloner.

Sure, thanks.

If you don't enable TRIM, then I suggest you uncheck "Put hard drive to sleep when possible" in the Energy Saver System Preferences so that the SSD's internal Garbage Collection routines have time to run when the computer isn't being used.

TRIM is a bit tricky as it requires both the OS and the SSD to operate correctly, but I've seen a lot of reports where TRIM doesn't always work as intended so data loss is possible. The Linux kernel has lots of block lists to prevent certain SSDs from automatically using TRIM (some SSDs' TRIM features aren't implemented correctly or has a bug). From the Linux community I've found that it is not recommended to use automatic TRIM, but to run a TRIM command manually once a week or so. I haven't read up enough to understand the details exactly how the two versions differ. Of course macOS is different as well, but these issues are why Apple does not automatically enable TRIM on third party SSDs and at one time did their best to prevent users from using TRIM at all for third party SSDs. I am not aware of any utility for macOS which you can manually initiate a periodic TRIM command like Linux has.

Thank you, helpful reply, but "Helpful" button is dimmed under your post… Don't know why…

Here is a Crucial article regarding their take on TRIM support:
