What Is Disk Contention?

Disk contention occurs when multiple processes try to access the same disk simultaneously. Most disks have limits on both the number of accesses (I/O operations each second) and the amount of data they can transfer each second (I/O data rate, or throughput). When these limits are reached, processes must wait to access the disk.
