An HDD has an average seek time of 3ms, a rotation time of 4ms, and a transfer time of 0.01s. What is the average I/O time?

Suppose we have a HDD with the following specifications:An average seek time of 10 msA rotational speed of 6000 rotations per minute.A data transfer rate of 40 MB/s.What is the expected throughput of the HDD (in KB/s) when reading a 4 KB sector from a random location on disk? You may ignore all other delay

A disk rotates at a speed of 6000 rpm(revolutions per minute). It has a seek timeof 10 milliseconds. The disk has 100 trackswith each track having 200 sectors. Findthe average access time of this disk.

In accessing a disk block the longest delay is due to A. Rotation time B. Seek time C. Transfer time D. Access time

Consider the following scenario: • A table has 500,000,000 rows. • Each row is 400 bytes. • Magnetic disk transfer rate is 1 gigabyte per second. • Assume 1 gigabyte is approximately 1,000,000,000 bytes.Assuming no free space, a table scan requires approximately how many seconds?

Assume 40% of the instructions are data accessing instruction. Let a hit take 1 clock cycle and the miss penalty is 100 clock cycle. Assume instruction miss rate is 4% and data access miss rate is 12%, what is the average memory access time?
