A:Answer Thank you for your question. After a little more of a deep drive on my part, reading what I could initially find on this topic, I pulled the M2 drive and checked under the sticker (Hiding something?) The labeling on the chip shows PHOENIX. I have the 2TB and the P/N ends in HALB. Most of the documentation I am finding says PHOENIX controller, BUT looking at the PASSMARK performance numbers, being significantly lower 19,026 than the original numbers for the drive at 25,158, I am suspicious, now. I have two of these drives (2TB) and one was manufactured 2021.06 and the other 2021.07. Based on the news story dates, I suspect it might be the "in-house" controller (Unless they still use the Phoenix in the 2TB model, and the 'in-house' in the 1TB and below) - BUT I'M NOT 100% SURE at this point. This will require additional digging... if this is true - I will be a little disappointed. I might start looking at other manufacturers that don't feel a need to mislead. Sad, because Samsung has been SOLID for a long time. Caveat emptor.
