What is storage latency?

The correct answer is B. The time required for a system to process a storage transaction. Latency is a measure of the time required for a sub-system or a component in that sub-system to process a single storage transaction or data request. It's akin to the propagation delay of a signal through a discrete component and is typically a function of hardware. For storage…

Explanation

Latency is a measure of the time required for a sub-system or a component in that sub-system to process a single storage transaction or data request. It's akin to the propagation delay of a signal through a discrete component and is typically a function of hardware. For storage subsystems, latency refers to how long it takes for a single data request to be received and the right data found and accessed from the storage media. https://storageswiss.com/2013/12/10/what-is-latency-and-how-is-it-different-from-iops/
