1 - About

Latency is the second performance characteristic of a storage device.

It's defined as the time needed to access a particular location in storage.

The relevant unit of measurement is typically:

It may make sense to separate:

  • read latency
  • and write latency,

and in case of sequential access storage:

  • minimum,
  • maximum
  • and average latency.
