I recently bought an ADATA Premium M.2 Gen 4 SSD for my PS5, paying about 93 CAD (68 USD) for it. The SSD shows 99% health and works fine, but its speed is only around 25% of what's advertised. I've checked the drive's health with Crystal Disk Info and HD Tune, and I haven't found any errors. My motherboard is an AORUS X470 Ultra Gaming, and I think I'm using the M2B socket, which has different specifications; I found it supports PCIe 2.0. I'm curious if the M2B socket is indeed the reason for the slower speeds, and can someone clarify what generation it actually is?

That totally makes sense! Having a PCIe 4 drive in a PCIe 2 slot means you’re losing a lot of potential speed. Just moving it to a PCIe 3 slot should definitely help, but keep in mind, it won't hit the full capabilities of the Gen 4 drive.
Yep, if your SSD is PCIe 4.0 and it's in a slot that only supports PCIe 2.0, you're definitely bottlenecked. PCIe 2.0 offers about 25% of the speed of PCIe 4.0. You should really check if you can switch it to the third slot, which might give you a nice speed boost as it's likely PCIe 3.0.
