Your startup SSD has SLOW write:
    Write speed: 70 MB/s
    Read speed: 463 MB/s
Where is this located Internally?
You can connect a good Thunderbolt connected SSD which is a lot faster.
What happened to the internal drive originally installed?
I think iDrive may be the cause since EtreCheck reported thus crash 60 times:

Try uninstalling pere iDrive's instruction and then reinstalling.
