I recently bought an Adata Premium M.2 Gen 4 SSD for my PS5, and even though it has 99% health and was pretty cheap at 93 CAD (68 USD), I'm not seeing the speeds I expected. It's working fine for some games like Street Fighter 6, which load much faster than before, but when I ran tests with CrystalDiskInfo and HD Tune, I noticed that the speeds are only about 25% of what's advertised. My motherboard is an Aorus X470 Ultra Gaming, and it seems I might be using the M2B socket, which supports PCIe 2.0. I can't find clear information on the M2B socket's capabilities. Can someone clarify how this setup impacts my SSD's performance?

Based on what you shared, your M.2 Gen 4 SSD should ideally run at PCIe 4.0 speeds. However, since you're using the M2B socket, which only supports PCIe 2.0, you're getting about 25% of the potential speed you should see with Gen 4. So yes, the socket's generation definitely impacts the SSD's speed.
So just to clarify, PCIe 2.0 means it’s older, right? If I switch to the PCIe 3.0 slot, I’ll see a better speed increase but won’t hit the max that the Gen 4 SSD can handle?
