Disk scheduling algorithms are algorithms designed and used for scheduling disk operations
Disk scheduling algorithms dramatically increase disk performance
Disk scheduling algorithms aims to minimize seek time in moving-head disk
There are several algorithms available to schedule the servicing of disk I/O requests

Some of the Disk scheduling related algorithms are listed here below:

- Anticipatory scheduling
- CFQ
- Deadline scheduler
- Elevator algorithm
- FIFO / FCFS (First Come, First Served)
- SSTF (Shortest Seek Time First)
- FSCAN
- I/O scheduling
- LOOK algorithm
- N-Step-SCAN
- C-SCAN (circular scan)
- Noop scheduler
- C-LOOK
