Sounds so interesting. Generally yes, while the health is not 100% according the bottom of the surface test images, the test seems complete without problems.
Yes, because of internal device cache and similar technologies, it is expected to see that on flash storage (SSDs, memory cards, pendrives) a write type test starts relatively quickly - and then, as we advance we got worse and worse write speed. This is completely normal and expected behaviour.
What kind of error message do you see when you try to partition/format the SSD? After the Reinitialisation, I'd expect no problems, generally then the SSD should be partitioned without problems.

Is your other SSD made by Crucial ?
There are some compatibility issues of Crucial SSDs with some motherboards / chipsets (and their older drivers). Some other topic (eg.
https://www.hdsentinel.com/forum/viewto ... 32&t=12514 ) discuss for example new problems.
So not sure, but maybe the chipset drivers would require an update as it may improve compatibility with this (or these) SSDs in general.
If possible, please use Report menu -> Send test report to developer option about this SSD (especially if you still have problems when you try to format it), would be nice to see the current situation (complete self-monitoring information and possible chipset/driver) as it may give further thoughts.
Personally I'd also try the following:
1) select Disk menu -> Surface test
2) select Write+Read test but do not start yet
3) select the Configuration tab in this window and on the right, select Write pattern = Random data
then start the test. It will overwrite all sectors with random data and then verify if the data could be read back and we receive back the REAL data what we wrote. This would confirm if all sectors of the SSD can really store and hold the information we wrote previously.
(The Reinitialise Disk Surface performs slightly similar, but that writes all zeroes in the last step and verify/confirm that we read back instead of any other data, to ensure that all sectors properly erased and clean. By the above method, you can verify if any non-empty data could be written, read back - without damages/corruption).
