Just as we know, there are two forms of RAID, one form is software-based RAID, and another is hardware-based RAID.


Software-based RAID occupies system memory, consumes CPU cycles and is operating system dependent. By comparing with other applications that are running concurrently for CPU cycles and memory, software-based RAID degrades overall server performance.
