If running an older, pre Recovery Partition OS version, you can access Disc Utility while booted from an alternate boot drive.

As the process is nearing completion, you should see a note along the lines of 'Trimmed Free Blocks'.

I've already determined that I should have enabled it initially.Īssuming you are running Safari, after you enable Trim as Mike describes, restart your Mac from macOS Recovery and run Disc Utility > Disc First Aid, on your system drive as described here:Ĭlick the 'Details' toggle to show you what is happening as the process proceeds. It's to determine if I can still turn it on, after the fact, and if it will do me any good to do so. this post is not about that, so let's not. I've seen arguments here about the necessity of enabling trim or not.

So the second part of my question is, how do I trim enable all the volumes, not just the startup drive? The Terminal command line to enable trim that we see out there is always for the startup drive, I've never found how to do non-startup volumes? Or does it turn it on for all SSDs at once? I'm running OS Sierra. I have the startup/system drive, my DP projects drive, and a library/sample drive. But the EVOs absolutely did need to have trim enabled. I definitely don't want to wear out the performance of the drives, but I wonder if it's too late to turn trim on? Would I potentially mess things up? And if it's not too late, would it even be beneficial? The E2 blade is an OWC product and they claim that it's not necessary to enable trim for their SSDs, but I have to confirm that with them tomorrow. I was actually advised not to by the store guy, because there were problems with the EVOs (turned out it wasn't really an issue with Macs, but I bought his story). Man, it was like buying a new computer! But. I now have only one 4TB spinner left, for storage/archiving. It started with the startup spinner needing to be replaced, but then I got SSD fever and bought more.

So this is why I said having TRIM is always better (than not having).Last winter I outfitted my old Mac Pro with 3 EVO 850s, and an OWC Accelsior E2 PCIe blade, all 1 TB. Even though they insist they don't need TRIM. The DuraWrite would even be helped by TRIM because there would be less data to be compressed and would result in even less write amplification. There is no direct TRIM replacement in the OWC's link.

No need to move invalid data around which increases wear and tear (write amplification) and wastes space. With TRIM, the SSD's controller can selectively carry only valid data onto new location during garbage collection. If it is containing data, even if that data is invalid, it can't just be overwritten like on an HDD, it has to be erased (to become vacant) first. That location needs to be in 'vacant' state. Problem number two: on an SSD, before a data can be written on a location.

So before that time comes, the invalid data will get carried from place to place in 'garbage collection'.

Without TRIM, the only time when the SSD's controller knows what data is invalid is when it receives a command from the OS to write on an LBA that is already containing data. It enables the SSD's controller to know what data is invalid/can be erased. So it doesn't know what data is valid (still in use) or invalid (deleted-not in use anymore). Now, problem number one on SSD's: when you delete a file on an SSD, the SSD's controller doesn't get to know or read the look up table.

And when the time comes for writing on that location, the HDD head just overwrites it, no fuss. On an HDD, when you delete a file, what happens is the HDD's 'look up table' gets updated so that the OS knows that location (LBA) can now be overwritten when needed.
