[SOLVED] Can I run 2 PCIE 4.0 4x SSD's at full speed?

[Nightmare17081]

Hi guys,

I currently have a Sabrent Rocket 4 Plus M.2 NVME drive paired with a Ryzen 5600x and Asus ROG X570-F Motherboard,

I want to get another M.2 drive but my question is will adding a 2nd drive slow down the first?

From what I understand I have 20 PCIE lanes and currently 16 is allocated to my graphics card and 4 to my SSD so adding another PCIE 4.0 4x drive will cause both of them to only run at 2x speeds? Even if I add another slower PCIE 3.0 M.2 drive I'm assuming this will cause my primary drive to run at 2x?
