RAID Level & Disk Mirroring: A Reflective Look

What is RAID 1 also known as?

a. RAID 0
b. RAID 1
c. RAID 3
d. RAID 5
Final answer:

Answer:

The RAID level that is also known as disk mirroring is RAID 1.

RAID 1 provides redundancy by writing data identically to multiple disks simultaneously, ensuring high data availability and data protection.

RAID stands for Redundant Array of Inexpensive (or Independent) Disks, which is a data storage technology that combines multiple physical drives into a single logical unit for improved performance, reliability, and/or data protection.

In RAID 1, also known as disk mirroring, data is written identically to two or more disks simultaneously. This provides redundancy, as if one disk fails, the data can still be accessed from the mirrored disk(s). RAID 1 offers high data availability and data protection, but it requires a larger storage capacity due to the duplication of data.
