WD Black WDS256G1X0C 256GB Write/Read speeds

Hello,

i just finished my built today:

R5 2600
Asrock B450m Pro4
Hyper X Predator 3600 DDR4 16 GB

And as Boot Device the M2 SSD from the Title.

I get about 1500 MB/S reading Speed and only 200 MB/S writing speeds.

The Pictures i seen on Amazon etc. are especially to the writing speed much higher.

Latest Bios is installed and WD Dashboard says everythings okay.

Are the Speeds okay, or can i try something else.

Greetings Shic3
