VERY slow 970 Evo Plus 500GB (MZ-V7S500B/AM) - Whole system slowwwwwwww

JUMP TO SOLUTION

I'm a long time SSD user, been a tech for long long time so you can make captain obvious assumptions. So before upgrade I had a 970 Evo (MZ-V7E500BW), threw a heat sink on it to cool it down, it rocked, blah blah, benchmarked fine too, everything is snappy as usual:

Then I upgrade to a 500GB 970 Evo Plus (MZ-V7S500B/AM) And it just crawls along. My whole system seems so so slow. I benchmark it and I'm always in the 0 or 1 percentile:

Samsung Magician as well:

Very poor in CrystalDiskMark too:

It looks fine in Crystal Disk Info:

It's in a Gen3 x4 (32 Gb/s) m.2 slot. On the Motherboard,  It is located in the lowest (and therefore coolest) M.2 slot: M2_2

MB says this slot is: 1 x Ultra M.2 Socket (M2_2), supports M Key type 2230/2242/2260/2280/22110 M.2 SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen3 x4 (32 Gb/s)

 

Yes, I have the latest driver (3.2). Yes, I've tried 3.1 and 3.0. Yes I've tried reinstalling windows FRESH. Yes, I've tried putting a heat sink on it (Makes it about 13 degrees C cooler) - AND I also put a 140MM FAN at full speed directly facing it.

 

I'm getting my butt kicked by this one. It's gotta be something stupid I'm not seeing. 

 

 

Relevant Specs:
Intel Core i9-9900KF
Asrock Z390 Phantom Gaming 4 (latest bios 4.4)
64GB Kingston HyperX 2133 C14 4x16GB (@2700)
Intel Raid 5 Volume 20TB (10TB x 3)  (not plugged into SATA3_1  or SATA3_0)  (Disabled when my m.2 slot is in use)
960 GTX

Just to update, in case anyone else is searching, it was for 100% sure the SSD.  RMA'd it and the new one is so so much faster. Benchmarks agree. So yes, these m.2 ssds can go "sort of" bad and get slower. The new benchmarks for identical system:
