Samsung 070 EVO Plus: What is Polaris?

[Jonathan]

Overclockers refers to the Samsung 970 EVO Plus as "Samsung 970 EVO Plus Polaris 500GB M.2 2280 PCI-e 3.0 x4 NVMe Solid State Drive".

AFAIK, Polaris was the slower controller used in previous versions of the EVO 960, but I understand that the 970 EVO Plus has the latest Phoenix controller. In the description, to what does "Polaris" refer? Or is its inclusion an error?

"Phoenix is a Samsung Polaris Gen 2 controller now delivering up-to 3,500 MB/s sequential read speeds on even the smaller 500 GB and 1 TB versions"

So if this SSD has a Phoenix controller, why is Overclockers including "Phoenix" in the description?
