Explanation:
RAID can be implemented in either hardware or software. Each type has its own issues and benefits. A
hardware RAID implementation is usually platform-independent. It runs below the operating system (OS) of the
server and usually does not care if the OS is Novell, NT, or Unix. The hardware implementation uses its own
Central Processing Unit (CPU) for calculations on an intelligent controller card. There can be more than one ofthese cards installed to provide hardware redundancy in the server. RAID levels 3 and 5 run faster on
hardware. A software implementation of RAID means it runs as part of the operating system on the file server.
Incorrect Answers:
B: RAID levels 3 and 5 run faster, not slower on hardware.
C: RAID levels 3 and 5 run faster on hardware, not software.
D: RAID levels 3 and 5 run faster hardware than they do on software.
