Disk 1 RAID 0
Disk 2 RAID 0
Disk 3 RAID 1
Disk 4 RAID 1
The disk 4 appears like "Degraded" when I boot my system. I belive that I have to rebuild the RAID 1. I'm having troubles of performance. What I have to do ????
Replace disk 4, then see your motherboard manual on how to rebuild the array.
You can do it automatically through the bios or through the operating system.
