Shortest Seek Time First (SSTF)

Shortest Seek Time First (SSTF) is a disk scheduling algorithm that manages how a hard drive's read/write head moves to access data. It selects the next request closest to the current head position, minimizing movement and reducing wait times. By always choosing the nearest request, SSTF improves efficiency and overall speed compared to other methods, though it can sometimes lead to delays for requests far from the current position. This approach helps optimize disk performance by prioritizing the quickest possible access to data.
