Solid State Drives (SSDs) are more efficient than Hard Disk Drives (HDDs) due to many reasons. SSDs store data on NAND chips therewith provide quicker data access and are less prone to physical damage as opposed to magnetic platters in HDDs.

Besides advantages, SSDs with TRIM command enabled have a drawback in data recovery. A TRIM command allows macOS to inform an SSD which blocks of data are no longer in use, and macOS can erase the unused blocks internally. Hence, whenever you delete any data from a TRIM enabled SSD, macOS immediately erases the unused blocks containing the data.

Although TRIM functionality benefits SSDs by letting them handle garbage collection more effectively and improve their lifespan by doing away with unnecessary writes. Nevertheless, TRIM is more a bane than a boon from a user’s data recovery point of view. Since from an HDD, you can recover your data easily even after deletion, emptying of Trash, or formatting of drive. Perversely, SSDs with TRIM enabled, the data recovery task becomes difficult, next to impossible.

• Apple’s SSDs have TRIM functionality enabled by design. Contrarily, you need to enable the TRIM command for a third party SSD if the TRIM Support is No.

Macbook with Samsung SSD Trim, etc I recently installed a Samsung Evo 850 on a mid 2012 MacBook Pro and it runs amazing. I've read a lot about enabling trim and/or using Samsung magician software.

Now, the question arises: “Is there a way to get back deleted data from a TRIM enabled SSD?” The answer is NO for an internal OEM drive. However, the recovery is feasible in many cases due to varied reasons, so try out Stellar Data Recovery Professional for Mac. The product’s innovative recovery engine may help you to restore your lost files from the toughest of data loss scenarios.

For Mac data recovery on TRIM enabled SSD, you must carry out the following steps:

1. Download, unzip and install Stellar Data Recovery Professional on your Mac
2. Launch the software and on the home screen select what to recover then click Next
3. The next screen depicts all drives connected to the system in the left-hand panel. Select the TRIM enabled SSD
4. Toggle on Deep Scan as an advanced scanning method. Click Scan to kick start the process
5. On the next screen, you are able to track the progress of the scan. As the software discovers recoverable items, it populates the items in a tree-view list on the left panel. Wait till the scan is over
6. When scan completes, click on any item from the tree-view list to preview it before recovery
7. When you’re satisfied with file previews, select the files you wish to recover and click Recover
8. The software prompts you to select destination to save the recovered data. Click Browse to specify a different storage location and click Save

At the end of the recovery process, you should have all your deleted data restored successfully at the destination you picked.

Data loss is a disheartening situation for anyone, and the complicated nature of technology makes it difficult to understand and resolve; but with products like Stellar Data Recovery Professional, you do not have to have a technical expertise, as it is user-friendly. All you need to do is install the product and follow the simple instructions it provides at each step of the way. Free download the software to perform Mac data recovery on TRIM enabled SSD.

If you could find the deleted files after deep scanning the TRIM enabled SSD, activate the software to save the files.

Cindori used to make as a free piece of software but as the mac OS has developed the needs for Trim software have changed. Trim Enabler is now $9.99 from Cindori. Why Is TRIM So Important?When the OS, (Mac, Windows or Linux) uses TRIM with a solid-state drive, it sends a signal to the SSD every time you delete a file. The SSD then knows that the file is deleted and it can erase the file’s data from its flash storage. Nothing special there then, after all that is how rotational drives work.

They don't actually delete the file, they tell the system that the space that was occupied by the 'deleted' file is now available for reuse and so can be overwritten. Unerase type apps depend on this fact so that if you should delete a file in error you should resolve that asap. The longer you leave it the less likely it will be possible to recover the file.With flash memory, it’s actually faster to write to empty memory than to write to full memory, which means that the memory should first be erased and then written to. This causes your SSD to slow down over time unless TRIM is enabled. TRIM ensures the physical NAND memory locations containing deleted files are erased before you need to write to them. The SSD can then manage its available storage more intelligently.What About Garbage Collection?There is also some debate as to whether Garbage Collection on its own is sufficient to keep an SSD drive in tip top condition.

So I asked Crucial about whether I could or should use the TRIM function on my M4 drive. This was their response. I do not normally recommend enabling the Force Trim command, as this can potentially corrupt or damage data being stored on the drive. As the M4 has built-in garbage collection, TRIM is not necessary for the drive to maintain performance.

In order to activate the built-in clean up, all you need to do is restart the computer while holding down the 'Options' key. This brings you to the Boot Manager screen, where you will leave the system for a period of 6-8 hours (typically overnight is the recommended time). This procedure gives the drive idle power, which allows the controller to activate the Active Garbage Collection.

The Garbage Collection will clean up any invalid data being stored on the drive. This sequence should only need to be done once every 2-3 months, depending on usage and writes performed on the drive. Proceed With CautionApparently, not all TRIM commands are the same. Different SSD drives have different protocols for the TRIM function. What this can mean is that if you enable the TRIM function on Mac OS 10.10 and above, it can only issue the Apple protocol for the TRIM command. Other brands may misinterpret this command and delete wanted data rather than unwanted data. The consequences of this can be huge data loss.So my advice to all Mac users is to think very carefully before enabling the Force Trim command unless you have either an Apple or SSD drive.

I have bought an Angelbird SSD drive for my Mac Pro Cheesegrater.
