Just 2.25TiB (after static data, etc) into the test, Kingston V+100's WA is already up to an apparent 4.17x
For reference, after 8.59TiB host writes and with more precise measurement, the Samsung 470 only had an apparent WA of 3.53x...and it ended up at 5.11x.
The M225->Vertex Turbo also had its WA initially climb then stabilize. Basically, wouldn't be surprised to see the V+100's WA go even higher then stabilize over the next few days.
(it is entirely possible my normal method of deriving PE cycles from MWI depletion is also not applicable here)
Current expected MWI Exhaustion is just 74.3TiB host writes, 1276 normalized (64GB) writes, and 11.4 write days.
Preliminarily, it looks like we may have a drive similar to the Samsung 470
