Z690-F ROG STRIX GAMING WIFI Motherboard PCIe questions

Level 7


Current specs:

i7 12700-KF,

z690-F ROG Strix motherboard

MSI 3080 ti Suprim X

OS drive: 1 x Samsung SSD 980 Pro 500GB NVMe (M.2_4)

Games drive: 1 x Samsung SSD 980 Pro 2TB NVMe (M.2_1)

storage drive: 1 x WDC 3TB Sata hard drive (chunky one)

I'm looking into getting some more storage and was wanting to get rid of the Western digital drive and utilising the remainder of my M2 slots.
I've been reading up however, that depending what slot you use, this can change how many channels your GPU uses.

If I use all four M2 slots, will this change the channels that my GFX card is currently running at (PCIe v4.0 x 16)?

Am i better off getting one M2 drive? 
Would getting a SSD instead be an option?

I'm just wanting to make sure I can get the right solution to not make any performance impacts.

Thanks in advance!

I'm not sure if using all 4 slots will reduce your GPU speed, the manual isn't clear. It says to refer to the bifurcation information on the support site, which I cannot find. 

Regardless, even if your GPU drops to x8, you will only get at most a 3-5% speed reduction. 

I would say consider a couple of hard drives if you want lots of cheap storage. That way, you can copy information from one drive to the other and then you have a backup in case one fails. A free program like FreeFileSynch is a great way to keep the data synchronised. I do this and it works great. Also consider external backup if your PC is stolen, but FreeFileSynch will backup to external drives as well. Then keep that external drive in a different location. Ideally, it's a good idea to encrypt your data drives with Bitlocker if you have Win 11 Pro.   

Just some things to help you decide what's best for you...
