IOPS – Input/Output operations Per Second

Input/Output operations Per Second, in short IOPS, is a computer benchmark specification of data carriers. It indicates how many input and output commands can be executed per second. Thereby the specification can be specified more precisely:

• Total IOPS
  Average number of inputs/outputs per second
• Read IOPS
  Average number of outputs per second
• Write IOPS
  Average number of inputs per second

The larger the IOPS value, the faster the storage medium. New storage media, such as an SSD, can reach up to 20-50,000 IOPS.
