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.

No need to move invalid data around which increases wear and tear (write amplification) and wastes space. How to enable TRIM on macOS Open the Terminal from /Applications/Utilities. 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. If it reads back APPLE it enables TRIM, if anything else, it. Optimize Performance Access advanced macOS tweaks to improve your performance or free up several gigabytes of disk space.

Designed to enhance your Mac Improving on all of the features that made Trim Enabler the 1 SSD utility for Mac users worldwide. 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.
