I recently bought a 2TB Adata Premium SSD designed for the PS5, and I got it for a pretty good deal at 93 CAD (approximately 68 USD). While it seems to be working fine, I'm noticing that the speeds I'm experiencing are only about 25% of what the SSD is rated for. I've run some tests using CrystalDiskInfo and HD Tune, and the health looks good with no errors. My motherboard is an Aorus X470 Ultra Gaming, which has different M.2 connectors. I suspect I'm using the second M2B socket, which might be slower. Online, I couldn't find a clear explanation about this M2B socket and its speed capabilities—it just mentions PCIe 2.0 support. Does this mean I'm stuck with lower performance?

You're correct, the M.2 Gen 4 SSD you bought is a PCIe 4.0 x4 drive. But if your motherboard's M2B socket only supports PCIe 2.0, that's why you're only seeing about 25% of the advertised speed. PCIe 2.0 slots can really bottleneck modern SSDs, which is why your drive isn't performing at its best. Just moving it to a PCIe 3.0 slot should give you a noticeable speed boost, but as you've observed, it still won't hit full Gen 4 speeds.
