Disk Throughput
Summary
Disk Throughput is a metric that measures the total amount of data that can be read from or written to a server's hard drive in a given period of time. It is typically measured in Megabytes Per Second (MB/s) and is important for systems architecture because it can indicate how efficiently a system can handle data storage and retrieval.
The formula for calculating Disk Throughput is:
Throughput = (Total Size of Data) / (Time to Read or Write)
For example, if you wanted to measure the Disk Throughput of a server that reads a 1GB file in 10 seconds, you would calculate it as follows:
Throughput = (1GB) / (10 Seconds) = 100 MB/s
Another example would be if you wanted to measure the Disk Throughput of a server that writes a 500MB file in 8 seconds:
Throughput = (500MB) / (8 Seconds) = 62.5 MB/s
