The crucial mx300 ssd has an app so you can upgrade the firmware in OS-X.

I enabled Trim about a month ago, and it has been working good.

To enable TRIM, first save all your open documents as this will reboot your Mac.

Terminal. 2) Type sudo trimforce enable.

Confirm that you want to enable trim.

Reboot your Mac. To verify that TRIM is enabled, click the Apple icon in the top left of your screen.

Choose About this Mac - System Report - SATASATA Express and look for the entry Trim Support.

When you delete a file from an SSD, the space needs to be erased first by the SSD controller.

Two gotchas. First, the minimum contiguous space that can be erased is often larger than what the file occupied so before erasure, all the still good stuff in that space has to be moved somewhere else first.

Second, the HD and the OS both know about file deletion making the space free, but the SSD controller doesnt, so when the good stuff is moved prior to erasure, the deleted stuff goes too.

TRIM is the function built into the OS that tells the SSD the deleted files space is erasable but its only on by default with Apple SSDs.

A key idea is that the space is flagged as available when the deletion takes place which means TRIM must be running continuously to get full benefit and any such benefit is lost for deletions prior to TRIM being enabled.

So there will be no sudden magical fix for a drive slowing down because the SSD controllers Garbage Collection has previously had to deal with secretly deleted files which are still taking up space.

The rep was very clear in stating that trim needed to be enabled.

In fact, he said that the SSD would eventually start throwing errors if trim was not enabled.

So I enabled trim on the terminal (sudo trimforce enable) after backing everything up.

Rebooted and running without any problems.

You will have to do your own research and make your own decision on the issueultimately it is your loss or gain.

All new SSD will perform well, it is over time when allocated blocks and pages become used, you start to see a loss of performance.

TRIM doesnt obviate the need for garbage collectionit works with garbage collection to more properly mark pages as stale.

And you dont need TRIM for garbage collection to workbut TRIM makes an SSDs garbage collection more efficient.

The advantage of the TRIM command is that it enables the SSDs GC (garbage collection) to skip the invalid data rather than moving it, thus saving time not rewriting the invalid data.

This results in a reduction of the number of erase cycles on the flash memory and enables higher performance during writes.

The SSD doesnt need to immediately delete or garbage collect these locations it just marks them as no longer valid.

This helps ensure that all storage cells are aged uniformly and maximum lifetime achieved.

No problems. In MS-Windows-10 I have the Samsung SSD app installed so I can upgrade the SSD firmware.

I think you maybe able to make a bootable USB firmware upgrade thumb drive.

Since the Samsung Evo SSD is designed for MS-Windows 7-10 PC and not for OS-X.

I would recommend an SSD that is supported on OS-X like the OWC SSD or Crucial MX300.
