Hi!
I have a build with i7-7700K, Asus Z170 MB (don't remember the model) and Samsung 850 Pro 256 connected to 6 Gigabit SATA port running Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina 10.15.3.
I've noticed that the write speed is very slow — about 80 MB/s. Read is OK, ~500 MB/s. I've tested with dd and BlackMagic benchmark with pretty similar results.
That's the system report:
What's wrong with my configuration? Write should be about 5x faster.
