Degraded and abnormal performance of my SN850 1TB SSD

Hi!
I have a problem with my main SSD which is a WD SN850 1TB, I bought it in September 2022 and I noticed that my SSD speed is slow. I did tests with CrystalDiskInfo and the performance is not up to par with the disk and I have the impression that the games load less well than before, although I have the latest BIOS update, Windows, AMD and the SSD microprocessor, I don’t understand.
Dashboard system no longer displays disk usage (I reinstalled the software but it still doesn’t work)


Here is my system:
CPU: 5700X3D
GPU: 7800XT
Motherboard: B550-Plus TUF Gaming

Does anyone have the same problem as me with their SSD? Do I have to open a ticket with WD?

Thanks !

most SSD slow after 50% filled with data, might be time for a larger capacity model

yes I understand that it is not good for an SSD to be almost full but it seems crazy to me that an SSD loses so much speed after being filled to more than 50% capacity, for me it is not normal especially for this range of SSD.

I have the 2TB version of the SN580 and it slows when above 50% capacity. I noted this when moving steam games when the speed fell but it eventually does get the job done.
