Which metric measures the number of bytes read or written per second?

• A. Latency
• B. IOPS
• C. Throughput
• D. Capacity

Answer: (C)

Throughput is the metric that measures the number of bytes read or written per second. It essentially quantifies the amount of data being transferred in a given period of time, which is crucial for understanding data transfer efficiency in high-performance computing and big data environments. High throughput indicates that a system can handle a large volume of data effectively, which is essential for tasks that demand rapid data processing and access. Latency, on the other hand, refers to the delay before a transfer of data begins following an instruction for its transfer. IOPS, which stands for input/output operations per second, measures how many individual read and write operations can be performed in a second, but does not directly account for the size of the data. Capacity refers to the total amount of data that a system can store, which does not indicate the speed of data transfer. Thus, throughput is the most appropriate metric for measuring the speed of data reads and writes in terms of bytes per second.
