Difference Between Seek Time and Transfer Time
Seek Time | Transfer Time |
---|---|
Time taken by the head to move from current track to the one where data is present. | Time taken to transfer data from the disk to the host system. |
Can vary a lot depending upon the distance between current and final position and how it has been instructed to go. | T = b/rN T is Transfer time, b is number of bytes to be transferred, N is number of bytes on a track and r is rotational speed in Rps |
Measure in Average Seek Time | Measure in Data Transferred in a unit time i.e. Second |
Usually in between 10-20 ms, depending upon the RPS and grade of Drive | It takes about 1 sec to transfer 30-60MB of data |
Eliminating unnecessary head development and making effective planning estimates. |
Maximising the components of information exchange while making use of high-speed interfaces. |
Navigational distance, machine capabilities, and scheduling algorithm. |
Components of information transfer, rotational speed, and information thickness. |
Difference Between Seek Time and Transfer Time in Disk Scheduling
The head’s seek time is the time it takes to move from the current track to the one containing the data. The amount of time needed to move data from the disc to the host system is called the transfer time. In hard drives, a head is present which is supposed to write or read from the magnetic disk. In this article we are going to discuss what are seek and transfer times and check the differences between them, Below is a detailed discussion of seek and transfer times:
