Bad RAID 1 performance

[atxcyclist]

So, I've set up two identical RAID 1 arrays on two different computers, one at my house and one at my office. They both use the exact same newly-purchased drives, but the one at my house gets much worse performance than the setup I have at work. The one at home I get about 97 MB/s both read and write, but the one at work I get 178 MB/s write and 263 MB/s read. The weird thing is, the work computer has a SATA II controller and the one at home has a SATA III. Is there something I should be looking at with caching or something? My home server also has an NVMe boot drive, so the controller shouldn't be getting any other requests since the only drives on there are these two in the array.

Chipset-based in both cases, AMD. Old one is a Dell XPS 7100, 785g I think. New one is an A88X.

Id stay away from chipset raid if you can, can you use software raid?

I'm running Windows 10 Home edition as this is just a file storage server, not sure if there's anything available for it. I may try a few settings in the BIOS as I have nothing stores on there that's not backed-up, possibly switching ports as well..

storage spaces will work fine on windows 10 home, so id give that a shot.

Found the problem. When I updated the BIOS to enable NVMe support it went wrong. It worked well enough to install an OS and drivers, but any attempt to do more difficult tasks resulted in instability and my BIOS would go back to defaults.
