I recently bought an Adata Premium M.2 Gen 4 SSD for my PS5, paying about 93 CAD (68 USD) for it, and while it's working, I'm only getting around 25% of the advertised speed. I checked its health with CrystalDiskInfo and HD Tune, and both tests showed no errors. My motherboard is the Aorus X470 Ultra Gaming, and I think I'm using the M2B socket, which seems to support PCIe 2.0, instead of the newer PCIe 4.0 that the SSD is capable of. I'd love some clarification on this M2B socket and how it affects performance!

Exactly! If it's in a PCIe 4 slot, it should at least double the bandwidth. Moving from PCIe 2.0 to 3.0 will improve your speed to about half of the original. So you're on the right path!
Your M.2 Gen 4 SSD runs on PCIe 4.0 x4, but if your M2B socket only supports PCIe 2.0 x4, that's definitely the bottleneck you're experiencing! So yes, you'll see speeds around 25% of what the SSD can do. Just to confirm, PCIe 2.0 means it's an older generation, so you'd need to switch to a PCIe 3.0 or 4.0 slot to really utilize the SSD's potential.
Got it! So moving it to a PCIe 3.0 slot will speed things up significantly, even if it's not full PCIe 4.0 speed, right?
Thanks for clarifying! I switched slots and noticed a decent improvement, but I'm still not maxing out. Just need to know if I can get closer!
