Access Time Calculator

How to Use the Calculator

1. Enter the seek time in milliseconds (ms).
2. Enter the rotational latency in milliseconds (ms).
3. Enter the data transfer time in milliseconds (ms).
4. Enter the controller overhead in milliseconds (ms).
5. Click the "Calculate" button to compute the total access time.
6. The total access time will be displayed in milliseconds (ms).

Understanding the Terms

Seek Time: This is the time it takes for the read/write head of a storage device to move to the correct track where the data is stored.
Rotational Latency: This is the time it takes for the desired sector of the disk to rotate under the read/write head.
Data Transfer Time: This is the time it takes to transfer the actual data from the disk to the controller or vice versa.
Controller Overhead: This is the additional time taken by the controller to process the read or write request.
