Consider a disk with an advertised average seek time of 6 ms, rotationspeed of 7,200 rpm, and 512-byte sectors with 500 sectors per track. Suppose that we wish to read a file consisting of 2500 sectors for a total of 1.28 Mbytes. Estimate the total time for the transfer when:
If the disk is rotating at 3600 rpm, determine the effective data transfer rate which is defined as the number of bytes transferred per second between disk and memory. (Given size of track = 512 bytes).

You have a disk with an average seek time of 3ms. Its rotation speed is 20,000rpm. The disk is organized as 512-byte sectors with 500 sectors per track. Assume that the disk uses sequential organization. How long would it take to read a file consisting of 3000 sectors? What is the total size of the file read in MB?
Suppose a disk drive has the following characteristics: -6 surfaces -16,383 tracks per surface -63 sectors per track -512 bytes/sector -Rotational speed of 7,200 RPM. Please compute a)The capacity of the drive b)The average rotational delay.
Computer Science Draw a sector representing one platter surface of a hard disk with sixteen sectors. On your drawing show a track, the sectors, and a single block. Place a magnetic head somewhere on your drawing. Show on your drawing the seek time, latency time, and read time for the block that you drew on the disk.
The capacity of hard disk with 16 platters, 1 K cylinders, 128 sectors per track, 512 bytes per sector is will be__?
1. A manufacture wishes to design a hard disk with a capacity of 60 GB or more (using the standard definition of 1GB = 230 bytes). If the technology used to manufacture thedisks allows 512-bytes sectors, 1024 sector/track, and 60% tracks/ platter, how many platters are required?
Computer science question: Draw a circle representing one platter surface of a hard disk. On your drawing show (and label) an example of a track, of a sector, and of a block.
Suppose that a disk drive rotates at 8000 RPM. It has an average seek time of 4 milliseconds. If its transfer rate is 15 Mbps, determine the average time it takes for a 15K byte request to be transferred from the time the disk starts the seek? From this, determine its throughput.
Question 1 Computer Science Assume updating one block of data to a RAID-5 storage takes c ms. What is the cost for updating two blocks of data to the storage? Give the reasons. • Hint: consider to store the blocks on the same disk, different disks in the same stripe, and different disks in different stripes.
