Understanding RAID (4.2)

Regardless of whether you have come across the term Redundant Array of Independent Disks or Redundant Array of Inexpensive Disks, you should know that you are dealing with the fault-tolerance concept. RAID is a technology that combines a considerable number of physical disks into a single logical unit so it can protect the data in the case of disk failure. Note that RAID is not a backup solution and it should never be considered as such.

Types of RAID (4.2.1)

Well-known RAID types are as follows:

• RAID 0: This is known as disk striping, offers higher read and write performance, but it is not fault-tolerant. On Windows Server 2016, you can create a striped volume if you convert the disk from basic to dynamic.
• RAID 1: This is known as disk mirroring, requires at least two disks, and offers excellent read and write performance. It works in such a way that all the data that resides on disk A is mirrored on disk B. In the case of disk failure, the RAID controller uses any...
