[Solved] "sudo trimforce enable" not found

[P1LGRIM]

Pilgrim,

Does this procedure also work with High Sierra?

Regards

Try it and see.
In High Sierra a lot of SSDs do not need Trim support and if you use the APFS it may actually decrease performance.

Thank you P1LGRIM, I just installed High Sierra, using TonymacX86's method, and have a fully functioning installation. I would loathe disrupting this so, thanks, but I will pass on Try it and see as if it doesn't work as it is supposed to I will the have to chase up how to reverse what I did. With my limited knowledge of using Clover that would be another adventure though it may be simple for the initiated.

Thanks again as I will now resolutely ignore forcing TRIM and instead, focus on using the system.

Ridiculously easy with Clover Configurator :

Just select it from the dropdown list of patches - Switch it on or off with the Disabled tick box.

Can you explain further? I've just installed High Sierra on a Samsung 860 EVO with APFS. Trim is disabled by default. Should I turn it on? And if so, is the clover method the only way or does the terminal command (sudo trimforce enable) have the same effect?

I've thought about reinstalling with HFS but don't want to deviate from a vanilla setup. Thank you!

Most modern SSDs have maintenance routines built in and don't need TRIM enabling in order to function perfectly well, in fact enabling TRIM may conflict with the drive's firmware and actually degrade performance.

Should I turn it on?

Your choice.

According to the Samsung specs page on the 860 EVO here, it has TRIM support and Auto Garbage collection. Not sure if that means built in...?

This is all so confusing, so many comments all over the net saying they're ok with disabling TRIM, some say it's required, others say stay away from APFS... etc.

Does TRIM enabling work the same via Clover as with the Terminal command?

Ask the developer.

I have two installs of High Sierra on two different drives; Intel 520 Series 180gb SSD and Samsung 860 EVO 500gb

I tried the command line TRIM enabler method on the Intel SSD (it's my backup and testbed install in case anything fails or I need to try out software without bogging down my main OS). Everything was fine except I had a longer boot by about 30 seconds. No big deal. Read speeds via BlackMagic app test hovered around 450mb/s while write speeds were around 175mb/s.

Applied the TRIM enabler to the 860 EVO; system seems just as fast, no issues and no delay in boot. Didn't check for read/write as I don't want any benchmarking tools on that drive as it's my main work drive.

Thanks again!

It's true a lot of modern SSDs have trim and garbage collection in their firmware. I haven't been convinced of the need to add OS-side trimforce for a few years now. No problems. Shows in System Report as Trim = No. Certainly don't experience quicker or slower boot times.

I think I need someone to explain why I'm wrong ...

A proper speedtest benchmark would probably put the discussion to bed. If you are still getting nearly 500mb/s read/write speeds, then yeah you're good.
