ASRock Rack EPC621D6I Installation guide

  • Hello! I'm your chat assistant. I've reviewed the user manual for SATA hard disk installation and RAID configuration. The document covers key aspects like setting up various RAID configurations, including RAID 0, 1, 5, and 10, using the Intel RAID BIOS. It provides detailed guidance on installing Windows OS with RAID, and some important precautions to consider before creating a RAID array. I'm ready to answer your questions about the devices described in this manual.
  • What RAID levels are supported?
    Can I use different sized hard disks in RAID array?
    What is the minimum number of disks to create raid 5 array?
    What is the minimum number of disks to create raid 10 array?
