Website with 500K visits/month and 30GB size. Should i use SSD VPS or MNVe VPS ?

Hello,

I have a newsblog wordpress website of 30GB size and 500K visits/month.
I am thinking of hosting it in a Contabo VPS.
I need the disk size offered with the SSD disk but i am worried about performance, so i am also considering NMVe disk.
Do you believe that there will be a significant decrease in performance if i use the SSD disk ?
Any advice will be much appreciated !!
