I went with the WD Black SN750 1TB drive in a TEKQ Thunderbolt 3 enclosure.

Since this would probably be my startup drive on my main computer for the foreseeable future (easy to migrate to a new mac by just plugging in an external), I decided to go for the higher performance of a NVMe drive as well. I had used a waterproof external ( Silicon Power Armor A80)* for work in the past for my startup drive so I wouldnвЂ™t have to bike with a laptop, so this setup was familiar/comfortable for me.

I decided to upgrade to an external SSD as my main drive, and use the internal Fusion drive as an cloned bootable backup. I was thinking about how I wanted to back up that 2TB drive when I had a different idea. Was easy enough to re-join them since I didnвЂ™t have any data on the machine.Д«eing a fairly high-end machine it was still very usable but not as responsive as my old MBA with an SSD I was replacing. Was my first time with a fusion drive, so didnвЂ™t even know they could be split into separate devices. I had purchased a used 27' 2017 iMac (3.8 GHz quad-i5, 40GB, Radeon 580) that came with a 2TB fusion that the previous owner has split. Reading this article was like deja vu, I went through almost the same process last fall.

Some people disagree strongly with claims like this, but thatвЂ™s beyond the scope of this discussion. For example OWC says this for the drives they sell. But even if your enclosure has support, your computerвЂ™s OS still needs to send the command.Д«ut it should also be noted that some SSD manufacturers claim TRIM is unnecessary. In theory, it is possible to run TRIM over USB if the enclosure supports UAS, since SCSIвЂ™s вЂњUNMAPвЂќ command performs the same function. If the trimforce command is something youвЂ™re not comfortable using, there is a commercial product, Trim Enabler which does the same thing, but with a really friendly GUI (and several bundled diagnostic tools). (DonвЂ™t forget to reboot after running this command - the change wonвЂ™t take effect until you do.) Whether this will work on USB devices or if it is reserved for other interfaces (e.g. You can, however, run the trimforce command to let it work on third-party SSDs. Out of the box, macOS will not even attempt TRIM on non-Apple hardware.

Not aware of a driver download for TRIM that works for USB though.
