Another weird POH count:

I notice that the drive has recorded 36,214 hours, but has only lost 5 points from the normalised Current value (5 = 100 - 95). At this rate, it is projected to hit the threshold at 82 years.
Weird.
"Drive Temperature" is a composite temperature which is derived from a weighted average of the temperatures reported by the real, physical, on-die temperature sensors on the controller and NAND flash ICs (or perhaps a discrete temperature sensor IC).
By "twist", I meant that a manufacturer could not make a 1TiB SSD, at least not without a convoluted design. Therefore, those people who insist on getting a 1TiB SSD instead of 1TB would be complaining in vain.
What is stranger still is that the IDEMA capacity of two 500GB drives exceeds the IDEMA capacity of a 1TB drive by 21168 sectors. This means that you can't clone a 2 x 500GB RAID 0 onto a single 1TB drive, for example.
On the subject of decimal and binary kilo/mega/giga/terabytes, one really needs to understand the historical background. I grew up with memory chips and storage devices during the late 1970s and early 1980s. RAM chips were, and still are, accessed via data and address buses. These were almost...
Unless these drives have been refurbished by the factory, I can't see what the seller could be doing to them to be able to legitimately make that same claim.
Also, these drives have new firmware architecture which isn't yet supported by professional data recovery tools. That makes me wonder...
I suspect that your USB enclosure is configured with a sector size of 4096 bytes. That might be something to keep in mind if you intend to transfer data between computers.
If you see "OK", I believe all that is telling you is that no SMART attribute has fallen below its threshold. That would apply to SATA, but I don't know how a partially degraded NVMe SSD would behave.
I guess that tool should work, although I don't like this stipulation:
"Place this program file on the same drive you'd like to test TRIM on, and run it."
I always thought TRIM/UNMAP was automatic, but now I'm not so sure.
You can test this by creating a file, then deleting it. Use a data recovery tool, eg DMDE, to recover the deleted file and then examine it with a hex editor, eg HxD (freeware).
