> They have no dumping capability like a PC brand, I.e. I didn't even know what compromise Samsung's non-Pro models made vs EVO and they are obfuscated in searches by the PRO models.

Ok, I think your first mistake here is assuming that retail SSDs are a priority for Samsung. What they actually care about are the SSDs they sell to PC OEMs, and the enterprise SSDs. They don't really need the retail product line to serve as some kind of experimental dumping grounds. The low-end models that make it to the retail product line exist because they already have similar models in mass production for PC OEMs, and they can make a retail version by changing from green solder mask to black solder mask and printing a new sticker. (The high-end retail models exist for much the same reason, but sometimes have more meaningful hardware differences because PC OEMs aren't so obsessive about maximizing scores on bad benchmarks.)
