- What does the superparamagnetic limit mean for disk drives?arrow_forwardThe same disk block is used by operating systems to read consecutive blocks of a file. What's the big deal about magnetic disks? Is the use of SSDs still relevant, or has this become obsolete? Are there any explanations for this?arrow_forwardHow much, if any, data can be recovered from a failed backup that was created with double parity in RAID systems?arrow_forward
- What does it mean for disk drives to have a superparamagnetic limit, and how does it impact the drives in any way?arrow_forwardDisk errors on computers may be corrected by resetting the CMOS to its factory defaults. Please elaborate on this.arrow_forwardBlocks of the same file are saved on the same disk block by the operating system. For what reason is it so critical to do so with magnetic disks? Is it still necessary to utilize SSDs, or does it no longer matter? Why is this so?arrow_forward

- Question 32 4 Points What is RAID 50? How is it constructed? What is the minimum number of drives needed? Why would you use it over another RAID level? Use the editor to format your answer Question 33 4 Points When would fou use software RAID? When would you use hardware RAID? What are the advantages of one over the other? Use the editor to format your answerarrow_forwardSome new disk drives support native command queuing or tagged queuing. What is that and why is it an improvement?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_forward
