Average Seek Time Calculator

Formula

The formula to calculate the Average Seek Time (T_avg) is:

\[ T_{avg} = \frac{T_{total}}{N} \]

Where:

\( T_{avg} \) is the Average Seek Time (ms)
\( T_{total} \) is the Total Seek Time (ms)
\( N \) is the Number of Seeks

What is Average Seek Time?

Average seek time is a measure of the time it takes for a hard drive’s read/write head to move to the track where the data is stored. It is an important performance metric for storage devices, as it affects the overall speed at which data can be accessed. The average seek time is typically measured in milliseconds (ms) and is calculated by dividing the total seek time by the number of seeks.

Example Calculation

Let's assume the following values:

Total Seek Time (T_total) = 500 ms
Number of Seeks (N) = 50

Using the formula to calculate the Average Seek Time:

\[ T_{avg} = \frac{500}{50} = 10 \text{ ms} \]

The Average Seek Time is 10 ms.
