You’re installing a new server with a RAID array, and you need to decide how to best implement your RAID solution. What is an advantage of using hardware-based RAID over a software-based solution?
A) Hardware-based RAID is less expensive
B) Hardware-based RAID has better performance
C) Hardware-based RAID is optimized for the operating system
D) Hardware-based RAID has better integration with the operating system
E) Hardware-based RAID provides a convenient source of vitamin C
The answer: B) Hardware-based RAID has better performance
Hardware-based RAID provides its own hardware for processing and takes much of the processing away from the operating system. Although it’s faster, hardware-based RAID requires the additional cost of specialized drive controllers. Hardware-based RAID is also invisible to the operating system, so there’s no optimization or integration with the OS running on the hard drives.
