Industry has agreed on a standardized scheme for multiple-disk database design, known as RAID (Redundant Array of Independent Disks). The RAID scheme consists of seven levels, zero through six. These levels do not imply a hierarchical relationship but designate different design architectures that share three common characteristics. a. Which of RAID 1 or RAID 5 would you use in the following scenarios and justify your choice: i. A transaction database that performs many thousands of updates per second. ii. A web server that serves almost entirely static web content. b. Compare different RAID levels RAID 0, RAID 1, and RAID 5 in terms of ability to withstand failure, performance, and space overhead required implementing the particular RAID level
