We can work this out as (time for one revolution of disk) / 500 = 6ms / 500 = 0.012ms. So the total time is 8ms + 3ms + 0.012ms ≈ 11ms. We can clearly see that getting to read the first byte of the sector takes a long time, but reading the rest of the bytes in the sector is essentially free. WebApr 2, 2024 · Because the R-W may be already present at the desired position or it might take a whole rotation to get the desired sector under the R-W head. But, if the current position of the R-W head is given then the rotational latency must be calculated.
