Hello.
I am getting terrible transfer speeds between two M.2 NVME SSD drives. Both drives are working perfectly independently and hit advertised max speeds. Also, both get amazing transfer speeds to other SATA6 SSD drives, USB3 drives, and even network share writes to an UNRAID server are solid. However, when I try to transfer files (huge or small) between the 2 M.2 NVME drives directly, my write times get destroyed and hover around 60 MB/s. I'll run through my specs below, but there has to be a bottleneck somewhere. I have tried everything I know to do (seasoned IT guy).... and this machine is a gaming beast. I have no other issues except for this oddity. I searched the internet for hours and cannot find anyone asking about this similar problem. I figured after 15 years of watching from the stands, I would finally register as a user and make a post. I am not sure what read/write times are expected between 2 of these drives on the same motherboard, but it has to be higher than 60 MB/s one would assume! Can you even get the max speeds of 3,000 MB/s between these drives? Let me know if you are! I know that each of these drives in the M.2 specific install slots I chose on this particular motherboard are getting full X4 PCIe Gen 3 speeds (Samsung Magician confirmed). All drivers, firmware, OS updates, etc. are done. I have even swapped the drives/slots on the Motherboard. Crystal Disk Mark 6 shows everything is normal. Samsung Magician shows everything is normal.
Core Hardware:
I am running Drive 1 in slot "M2M" (Above Graphics Card) and Drive 2 in slot "M2A" (Below Graphics card). See the link below for a complete breakdown. In these slots (without using SATA ports 4/5), I have no motherboard bottlenecks or anything disabled for my hardware architecture.View: https://www.reddit.com/r/gigabyte/comments/a1u57t/z390_auros_ultra_m2_question/
I am dying to figure this out. Let me know what you need. I have lots of documentation and screenshots ready. Thanks in advance for any help!

Core Hardware:
- OS: Windows 10 Home 64-bit
- Motherboard: GIGABYTE Z390 AORUS ULTRA LGA 1151
- CPU: Intel Core i9-9900K
- RAM: Corsair Vengeance Pro 32GB DDR4 RGB
- PSU: Corsair HX-1200i
- Graphics Card: EVGA Nvidia GeForce RTX 2080 Ti
- OS Drive (SATA6): Samsung SSD 850 EVO 250GB (Firmware EMT02B6Q)
- Drive 1 (M.2 NVME PCIe): Samsung SSD 970 EVO Plus 1TB PCIe Gen 3 X4 (Firmware 1B2QEXM7)
- Drive 2 (M.2 NVME PCIe): Samsung SSD 970 EVO Plus 1TB PCIe Gen 3 X4 (Firmware 1B2QEXM7)
- Other Drives: I have X3 Samsung SSD 850 EVO 1TB drives in Raid-0 3TB setup. Transfers to this volume are very high. I also have X3 Seagate Backup Plus 8TB USB3 drives attached. Transfers to any of these 3 drives from either of the 2 NVME are as expected.
