Hi, I would like to ask you for help with solving of the problem I have with SN550 1TB, model number WDC WDS100T2B0C-00PXH0, firmware 211210WD.
From some reason, I have half 4K write speeds comparing write speeds I can see in reviews, for example on Guru3D.com.
I´m attaching my results in Crystal Disk Mark and also the screenshot from Guru3D.com
Same bad results are in ATTO.
At first, I thought I bought the defective piece so I bought another one to check.
Same speed results with the second one so I think there must be something wrong with my PC setup and not with SSD itself.
AMD RYZEN 1600 @3,7GHz on all cores
ASUS ROG STRIX B350-F GAMING
16GB RAM ADATA XPG 3000 (2x8GB)
1x SATA SSD SAMSUNG 840 EVO 120 GB (system only)
2x SATA HDD SEAGETE 2TB (data)
All drivers, including AMD chipset driver are up to date.
WD Dashboard and firmware up to date.
Windows 10 up to date.
Any idea what might cause this problem?
I will be grateful for every advice.
