Creating a RAID array is a technique for generating live backups of physical hard drives, although doing so will reduce the available capacity of the hard drive. Alternatively, would you want to have backup at the expense of half your available disc space? When it comes to a home computer system that has regular power outages that might result in hard disc failures, which form of RAID is the best choice?
A method for doing live backups of physical hard drives is to set up a RAID array, however doing so will diminish the hard drive's capacity. Would you rather have backup at the cost of using up half your disc space, as an alternative? Which kind of RAID is the best option for a home computer system that often experiences power outages that might lead to hard disc failures?

- Creating a RAID array is a way for producing live backups of physical hard drives; however, doing so willower the amount of available capacity on the physical hard drive. Alternatively, would you like to have backup at the cost of half of your available disc space? The ideal RAID configuration for a home computer system with frequent power outages that may result in hard disc failures is determined by the frequency of power outages.arrow_forward6. The RAID level which mirroring is done along with stripping is a. RAID 1+0 b. RAID 0 c. RAID 2 d. Both a and barrow_forwardRAID is a technique used to offer live backups of physical hard drives even if it reduces the hard drive's usable capacity. Would you prefer to have backup at the expense of about half of your disc capacity, or the opposite?

- Answer the following regarding RAID levels.a. Before adding the redundancy data, our RAID drive has 4 disk drives. If we choose RAID 1, how many extra drives do we need to add to store redundancy? RAID 5? RAID 6?b. We decide to use RAID 0 because we want our RAID drive to support multiple accesses as much as possible (that is, multiple different processes accessing disk simultaneously). Should we use small stripes or large stripes? Explain.c. RAID 4 is not used, why not? What RAID level would we use in place of RAID 4?arrow_forwardIn a RAID 5 configuration of four 1TB solid state disks, the total available storage is ___ TB. Enter the number in TB only, e.g., 7.arrow_forwardWhich RAID settings are the most cost efficient while yet providing enough redundancy?arrow_forward
- To what extent, if any, is it possible to restore data that was lost from a backup created using double parity in RAID systems?arrow_forwardHow do "error recovery controls" (ERC) help HDDs in RAID setups?arrow_forwardIt is up to a database administrator to decide how many drives make up a single RAID 5 array For example: How much does it cost? How long will it last? How well will it work after it breaks down? How well will it work while you're rebuilding?arrow_forward
