- By inspection of the disk specification in Figure 7.15, what can you say about whether the disk drive uses zoned-bit recording?arrow_forwardCompare the disk specifications for the HDD and SSD in Figures 7.15 and 7.17, respectively. Which items are the same? Why? Which items are different? Why?arrow_forwardA company that has engaged in a business that requires fast response times has just received a bid for a new system that includes much more storage than was specified in the requirements document. When the company questioned the vendor about the increased storage, the vendor said he was bidding a set of the smallest-capacity disk drives that the company makes. Why didn’t the vendor just bid fewer disks?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_forwardWhat is the average time to read or write a 512 bytes sector for a disk? The advertised average seek time is 5 ms, the transfer rate is 40 MB/sec, it rotates at 10,000 RPM, and the controller overhead is 0.1 ms. Assume the disk is idle so that there is no queuing delay. In addition, calculate the time assuming the advertised seek time is three times longer than the measured seek time.arrow_forwardSuppose a disk drive has the following characteristics:1. Six surfaces2. 953 tracks per surface3. 256 sectors per track4. 512 bytes/sector5. Track-to-track seek time of 6.5ms6. Rotational speed of 5,400rpmQ.) What is the capacity of the drive?arrow_forward
- Suppose a disk drive has the following characteristics:1. Four surfaces2. 1,024 tracks per surface3. 128 sectors per track4. 512 bytes/sector5. Track-to-track seek time of 5ms6. Rotational speed of 5,000rpmQ.) What is the capacity of the drive?arrow_forwardSuppose a disk drive has the following characteristics:1. Five surfaces2. 1,024 tracks per surface3. 256 sectors per track4. 512 bytes/sector5. Track-to-track seek time of 8ms6. Rotational speed of 7,500rpmQ.) What is the capacity of the drive?arrow_forwardThe need of wear leveling in solid-state drives is not something that can be overstated. Wearleveling, as we have previously discussed, is fundamental for the constant updating of virtual memory pagefiles. Why does wearleveling exacerbate the problem with pagefiles?arrow_forward
- 108. Which of the following is a measure of reliability of a disk? a. Seek time b. Average latency time c. Mean time to failure d. Average seek timearrow_forwardExplain how a DVD manufacturer can advertise that a DVD can hold 4.7 GB, but Explorer reports theDVD capacity as 4,706,074,624 bytes or 4.38 GB.a. Manufacturers are allowed to overadvertise their products.b. The manufacturer measures capacity in decimal and the OS measures capacity in binary.c. The actual capacity is 4.7 GB, but the OS requires overhead to manage the DVD and the overheadis not included in the reported DVD capacity.d. The DVD was formatted to have a capacity of 4.38 GB, but it could have been formatted to have acapacity of 4.7 GB.arrow_forwardSuppose a disk drive has the following characteristics:1. Four surfaces2. 1,024 tracks per surface3. 128 sectors per track4. 512 bytes/sector5. Track-to-track seek time of 5ms6. Rotational speed of 5,000rpmQ.) What is the access time?arrow_forward
