Hello.

I have a WD Black PCIe SSD with the following specs:

256GB
Up to 2,050 MB/s Read
Up to 700 MB/s Write

I'm getting 90% Write speed from its advertised speed in Windows 10 but with macOS Mojave formatted as APFS, I'm only getting 200 - 250 MB/s. Read speed is okay as I'm getting up to 1500 MB/s.

Is this normal in Hackintoshes/macOS or I have some rouge misconfigurations?
Where should I start troubleshooting?

Thanks.
