Understanding RAID Concepts

What does RAID stand for?

• Random Access Integrated Drive

• Redundant Array of Independent Disks

• Rapid Array of Indexed Disks

• Redundant Allocation of Internet Drives

Why would someone use RAID?

• To make the computer look cooler

• To decrease storage space

• To increase data reliability or performance

• To make the computer run slower

Which RAID configuration is known for mirroring without parity or striping?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

What is parity in the context of RAID?

• A method to speed up the read and write operations

• A way to make the drives work independently

• Data stored to help rebuild data in case of a drive failure

• The process of dividing data into blocks

What is the difference between hot swap and hot spare in RAID systems?

• Hot swap is for adding storage, hot spare is for replacing failed drives

• Hot swap allows you to remove a drive without shutting down, while hot spare is an extra drive that automatically replaces a failed one

• Hot swap is a type of RAID configuration, hot spare is a backup drive

• There is no difference; they are the same thing

Which RAID configuration is known for striping with parity?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

What is the main advantage of hardware RAID over software RAID?

• It is cheaper

• It uses the computer's CPU to process RAID

• It has its own processor to manage RAID, reducing the load on the computer's CPU

• It can only be used with certain types of hard drives

Which RAID configuration offers no redundancy?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

What is the purpose of a hot spare in a RAID configuration?

• To provide additional cooling to the system

• To serve as a backup drive that automatically comes online if another drive fails

• To allow for faster data access speeds

• To store extra copies of data for security purposes

Why might someone choose software RAID over hardware RAID?

• It provides better security against hackers

• It is generally less expensive and easier to configure

• It offers faster data transfer speeds

• It supports a larger number of drives
