I want to get a m.2 drive, but concerned about pcie-lanes

Hello,

I've been searching for a while on the net, but couldn't find the answer to my situation.
I have a z370 maximus hero x wifi with an 8700k and a 1080ti installed. I want to get an m.2 drive, but currently I have installed a usb expansion card with 4 seperate ubs-controllers on the pcie x4_3 slot. I also have two 2.5 ssd installed. I'm wondering if there will be any issues or limitations if I install an m.2 drive on my motherboard? I'm running out of space so a new drive is needed.

I would idealy keep both my 2.5 drives, but if there is some better way to configure this by removing one (one is quite old and small so not the biggest loss). I need the usb expansion card though (alot of periperals because of simulators and stuff).

If someone could help me out, I would appreciate it.

You will be fine, the m.2 lane are tie to the chipset. If you set it at 4x sata 5 and 5 will be disable the the 4 other port will still work. If you dont mind me asking why the usb controler card ?

Hello and thank you for answering my question. I needed the usb-card because I have a joystick, a throttle, vr headset, motion rig, pedals and wheel among other things. It was getting quite cramped.

I don't quite understand this sentence though: 4x data 5 and 5 will be disabled. Care to do a eli5 or point me to a resource I can read?

Page 3-19 of your motheboard user manual,

Sata is the interface of your 2.5 hd,you have a total of 6 port ,enabling your m.2, at 4x will disable port 5 and 6.

You have 2 m.2 port both support nvme, take the opportunity to move your os on 1 .

Just as a suggestion im using complete hotas system as well and ended up using a usb c 3.1 hub

Thank you again!

I have two 4 usb expansion hubs connected. Just now they are not fully in use, got 3 free slots. My simrig is a collection of different motion equipment and also gear sticks, separate pedals and soforth. The reason I bought an extension card was to avoid any saturation of the usb controllers. I got my vr headset, motion rig to the expansion card. Now how realistic is it that I would saturate my usb controllers? Probably not much, but the card had a good price so I thought, why not.

Do people use nvme drives just for their is or is it ok as a general use drive? Wondering if I should buy a 500gb or 1 GB nvme.
