MacBook Pro 15 2017 256GB - Slow SSD

Hi,

I just bought a Macbook and tested the SSD speed with Novabench.

The write speed is quite disappointing and seems a little off the road.

360 mb/s doesn't seem right.

The capacity of the SSD is 256GB and I'm running High Sierra 10.13.3.

Does anybody have had the same experience or can provide a solution for this?

I'm grateful for any advice.

After I installed some apps I decided to reset the OS. Maybe that's a fact also to be considered.

Thanks a lot for any answers.

Best,

Yannick
