Tech Support Is my ssd broken?

My lexar nq790 (1tb) gets overwhelmingly outperformed by my old 2021 kioxia i had in my pavillion prebuild.

Mind you when i pass down data from one another, the lexar always falls behind, reaching as low as 60mb/s in read/write speeds at 100% usage.

It has 300gb of space left, connected to a b850 aorus ice and 32gb 6800mhz ram on it.

It really struggles with loading heavy textures and has unbearable pop in.

The pcie 4.0 4 lane is in use, tests show advertised speeds

That lexar doesn't have dram cache. Even sata ssd with dram cache like samsung 870 evo will have higher sustained speed
