In a system with high CPU utilization, which of the following will help the MOST to minimize the performance impact of parity overhead in RAID 5?

Using SAS drives improves disk I/O performance and reliability but does not offload the parity calculation process from the main CPU.

Triple Channel RAM improves memory bandwidth for the main CPU but does not directly offload the CPU-intensive parity calculations performed by RAID 5.

Using Solid State Drives (SSDs) significantly boosts disk I/O performance but does not offload the parity calculation process itself from the main CPU, which is the primary concern for high CPU utilization.

A hardware RAID controller contains a dedicated processor and memory to handle RAID parity calculations and disk management, offloading these CPU-intensive tasks from the main system CPU. This significantly reduces the performance impact of RAID 5 parity overhead, especially when the main CPU is already under high utilization.
