Describe RAID level 5. What are the advantages of using RAID level 5 over other types of RAID?

Correct Answer

verifed

verified

RAID level 5 replaces RAID levels 3 and 4, and is the most common RAID configuration as of this writing. It is commonly referred to as disk striping with parity. As with RAID levels 3 and 4, it requires a minimum of three hard disk drives for implementation; however, the parity information is not stored on a separate drive, but is intermixed with data on the drives the set comprises. This offers better performance and fault tolerance; if any drive in the RAID configuration fails, the information on the other drives can be used to regenerate the lost information after the failed hard disk has been replaced. If two hard disks fail, the system must be restored from a back-up device.

Match each term with the correct statement below.

Premises
File that lists all of the system events that occurred during the installation, such as the creation of user and group accounts.
The unique identifier used with peripheral components.
Improves efficiency and performance on the system by allowing a device direct access to physical memory via one of a limited number of unique channels.
Files that can be used in conjunction with a writable CD-R/CD-RW drive to create installation CD-ROMs.
A type of RAID level 0 that consists of two hard disks that are seen as one large volume.
A standard that is primarily used to shut off power to peripheral components on portable laptop computers, and that is supported only by the BIOS of the computer.
The act that a processor performs on system devices to see if there are tasks to be run.
File that contains a list of packages that were installed as well as a list of those that were not installed.
A standard that allows users to configure power options from within the operating system rather than from the BIOS setup utility.
