Hi all! I believe this is my first post here on the forums, but boy have I received a lot of guidance on going all in on my Hackintosh build.

I've been using it for a month or so now after purchasing a RX580 8GB for that native support. It is perfectly stable and edits video wonderfully.

I have however noticed that my SSD read and write speeds are slower than they used to be on Windows, after doing some digging I found that the "Negotiated Link Speed" for both my SSDs are 3 Gigabit. I tried searching online but can't really find guidance on this. I have enabled trim using trimforce. I do know that both the SSDs support 6 Gigabit SATA III and that the motherboard does as well - but performance on OS X seems consistent with SATA II speeds.

System specs:
MSI H81M-P33
i7 4770
16GB 1600MHz
Gigabyte Aorus RX580 8GB
Running 10.14.4

SSDs:
500GB WD Blue (OS Disk)
240GB WD Green (Scratch Disk)

My internal 4TB Seagate HDD is running at 6 Gigabit and performing as expected.

See the screenshots below

Any ideas?

You only have two SATAIII ports.

Oh my really? I'll switch the cables around and check it out. Thanks!

Should have probably started with that eh.
