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?

- 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_forwardUsing a RAID array to create live backups of physical hard drives is a way for increasing the available capacity of the hard drive. Alternatively, are you willing to sacrifice half of your available disc space for backup? Which kind of RAID is the best solution for a home computer system that has regular power outages that might result in hard disc failures?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_forward
- 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_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? Which form of RAID is ideal for a home computer system that often endures power outages that might cause hard disk failures?arrow_forward2. Which level of RAID refers to disk mirroring with block striping? a. RAID level 1 b. RAID level 2 c. RAID level 0 d. RAID level 3arrow_forward
- These cylinder requests come in to a disk driver. The disk driver code can only buffer five requests at once. Requests for tracks 13, 21, 11, 80, and 65 come in. The order of the requests be processed are 13, 21, 11, 80, and 65. This indicates the seek algorithm used is: C-SCAN RAID FIFO SSFarrow_forwardAlthough the capacity of the hard drive will be reduced when a RAID array is created, it is a method for creating live backups of physical hard drives. As an alternative, would you want to have backup without giving up half of your disk space? Which kind of RAID should be used on a home computer system when there are regular power outages that might lead to hard disk failures?arrow_forwardFollowing the working principles of RAID Level 1 array, how you would like to fill the following physical disks from the stripes available in logical disk in the given digram.arrow_forward
- Concurrent chunks of a file are attempted to be saved on successive drives. Is there a reason why doing so is so critical for magnetic disks? Is it still vital to utilize SSDs if they are available, or is it a waste of time? Why is this so?arrow_forwardQuestion 32 4 Points What is RAID 50? How is it constructed?
