Q

What is the minimum number of drives required for RAID 1?

A

Two drives.

17
Q

What is the minimum number of drives required for RAID 5?

A

Three drives.

18
Q

What is the minimum number of drives required for RAID 10?

A

Four drives.

19
Q

What is a common use case for RAID 0?

A

Video editing and applications requiring high performance but no redundancy.

20
Q

What is a common use case for RAID 1?

A

Data backup and systems needing high availability.

21
Q

What is a common use case for RAID 5?

A

Servers requiring redundancy and performance.

22
Q

What is the main advantage of RAID 10?

A

Combines the speed of RAID 0 with the redundancy of RAID 1.

23
Q

What happens if a single drive fails in RAID 0?

A

All data is lost since there is no redundancy.

24
Q

What is the difference between hardware RAID and software RAID?

A

Hardware RAID uses a dedicated controller, while software RAID uses the operating system.

25
Q

What should you check before installing a storage device?

A

Ensure compatibility with the motherboard’s SATA, NVMe, or other ports.

26
Q

What is the purpose of a storage controller?

A

Manages the connection between the motherboard and storage devices.

27
Q

What is the purpose of formatting a storage device?

A

Prepares the device for use by creating a file system.

28
Q

What are common file systems used on storage devices?

A

NTFS, FAT32, exFAT, and ext4.

29
Q

What is the purpose of partitioning a drive?

A

Divides a storage device into separate sections for better organization and usage.

30
Q

What is the difference between primary and extended partitions?

A

Primary partitions are bootable, while extended partitions can hold multiple logical drives.

31
Q

What tool can be used in Windows to manage storage devices?

A

Disk Management.

32
Q

What is a common tool for monitoring drive health?

A

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology).

33
Q

What is a key consideration for installing multiple drives in a RAID configuration?

A

Ensure all drives have similar capacity and speed for optimal performance.
