The PERC H730 Adapter is a RAID (Redundant Array of Independent Disks) controller card used in Dell PowerEdge servers. It is responsible for managing multiple hard drives in a RAID configuration to improve data storage performance and redundancy. The PERC H730 specifically supports both hardware RAID levels and features such as data protection, hot-swapping, and RAID management.

To ensure the RAID controller functions correctly, you need the Windows driver for the PERC H730 Adapter. This driver allows the operating system to communicate with the RAID controller, enabling it to detect and manage the connected hard drives properly.
