NVMe PCIe x4 SSD on M.2 PCIe x2 slot

Hey there, i'm about to get a new SSD for my PC, and before spending the money i have some doubts about my decision i would like to clarify

 

First, my mobo is a B450 Aorus Elite, it has 2 M.2 slots, one of them full lenght (22110) with compatible with SATA and PCIe 3.0 x4 and the other one half lenght (2280) and support only for PCIe 3.0 x2

 

About the drive, i'm aiming for a Crucial MX500 1TB, wich is a PCIe x4 SSD

 

My first M.2 slot is already taken by the main SSD, wich i use for the OS and other stuff, i can't really use it. Will a PCIe x4 SSD work on a PCIe x2 slot? How much performance will be lost if it does? Will it be worth it?

 

Thanks!

That's not a PCIe 4x drive, it's a SATA one. It will not work in the second M.2 slot.

Wait, the label says it's a PCIe drive ô__o

Well, i'm not exactly knowledgeable when it comes to M.2 drives, it's an unknown field for me. What would be a good option for a PCIe M.2 drive without breaking the bank? I have a limited budget.

That's not an MX500, so make up your mind first

Kingston A1000, WD SN550 etc. Preferably not QLC like P1 or 660p

Loiking into it. Seems like if i want to keep it below 150 € i'll have to stay on the 500 GB mark :/

 

EDIT: The main question is still unanswered though...
