Asked to build a 512 TB of usable space.
Given:
-10 TB, 12 TB, 16 TB hard drives
-Limited to only a maximum of 30 hard drives
Question: What type of RAID array you would use? Note that you can use any of the given hard drives for this but maximum is 30 hard drives. Remember after RAID, the usable space should be totaling up to 512 TB. Show your work.

- 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?Which of these benefits does a RAID 0 storage system provide? Check all that apply. Group of answer choices a. Fault Tolerance b. Better read performance compared to a single disk c. Increased write performance compared to a single disk d. Decreased cost of storage per GB compared to a single diska) RAID is a method to create live backups of physical hard disks but creating RAID will decrease the usable capacity of the hard drive. would you prefer to have backup at the cost of half of your disk space? What type of RAID would be better for a home based computer setup that has frequent power failures that could cause hard disk failures? b) Sequential and direct access are two methods to locate data in memory. Discuss why major devices now a days use direct access?How can we convert data that is written on a device that supports only sequential access to a device that only support direct access method? c) There are number of types of digital memory available, such as hard disk drive (HDD), random access memory(RAM), solid state drives (SSD) and cache memory. Is there an advantage to having multiple standards or would it be beneficial to consumers if there was only one memory standard, such as just the various sizes of SSDs? Would having a single standard be less expensive and more…

(round to nearest integer) b)How many read IOPS will there be in this system with RAID 5 array of 6 disks? don't copy from other sources I will downvoteWhat is RAID? RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDs) to protect data in the case of a drive failure. There are different RAID levels, however, and not all have the goal of providing redundancy. How RAID works RAID works by placing data on multiple disks and allowing input/output (I/O) operations to overlap in a balanced way, improving performance. Because using multiple disks increases the mean time between failures, storing data redundantly also increases fault tolerance. RAID arrays appear to the operating system (OS) as a single logical drive. RAID employs the techniques of disk mirroring or disk striping. Mirroring will copy identical data onto more than one drive. Striping partitions (Links to an external site.) help spread data over multiple disk drives. Each drive's storage space is divided into units ranging from a sector of 512 bytes up to several megabytes. The…

Could you please verify? This is slack space only from the total of 10 clusters which have been counted and used what is needed and not total slack space for whole drive 16GB. The question mentioned on the begining: On a 16 GB hard disk drive (HDD), Thank you for clarify this info.The amount of usable storage space on a hard disk may be affected, however, if RAID is utilized to provide live backups of the underlying physical drives. Is it really worth it to sacrifice half of your disk space to preserve a backup? How might a home computer with regular power outages safeguard its hard drives? What kind of RAID configuration would be best?

Answer the questions in the table below by writing (1) yes (or no)(2) yes (or no).....(6) yes (or no) Can improve capacity? Can improve access speed? Disk caching (1) (2) RAID (3) (4) File compression (5) (6)RAID is predisposed to take into account ordinary rotating magnetic disks as a starting point. Is it required to use RAID for SSD storage? If this is not the case, does this make SSD storage a little more inexpensive for businesses? Is it important to have redundant disks, and if so, do they have to be solid-state drives (SSDs)?
