If the option to create a RAID 5 array is not available in Disk Management, what should you do?

When the option to create a RAID 5 array is not available in Disk Management, installing an add-on RAID controller is a practical solution. Disk Management in Windows typically does not support creating RAID configurations beyond basic RAID levels or requires specific hardware capabilities.

A dedicated RAID controller card can provide advanced RAID options, like RAID 5, which includes striping with parity for improved fault tolerance and performance. The add-on controller manages multiple hard drives more effectively and can provide the necessary configuration options that the built-in Disk Management lacks.

This approach is particularly useful when you need the robustness of RAID 5 for data redundancy and improved access speeds, as the existing system may not support such configurations natively due to hardware limitations or software restrictions.
