New Intel RST RAID 10 rebuildling but no disks are failed

I just set up a new RST RAID 10 array comprised of 3x HGST Ultrastar 7k4000 4TB drives and 1x WD Green 4TB drive. I plan on swapping the WD green out, but I was sent a bad drive so it'll do for now.

So, the problem is that I created the array and initialized it. I started copying about 2TB of data to it and I just checked and noticed the tray icon says the array is rebuilding. If I open the control panel and look at the array, none of the disks report an error. What's going on here? It also seems to be writing pretty slow. This copy has taken over two hours by now.

The OS is Windows Server 2012R2, fully updated.

Sounds like it is doing the initial RAID rebuild in the background. That is now basically a standard feature, which allows you to use the array, in a slightly performance-degraded state, while the rebuild completes in the background.

IOW, don't worry about it.
