Data Transfer Rate Calculator

Benchmark an actual backup, migration, or copy job's real throughput.

Useful for benchmarking real-world jobs

This is a simple after-the-fact calculation — time an actual backup or file copy, plug in the numbers, and you get a real throughput figure to compare against a drive's or network's rated speed.

Bottlenecks aren't always where you'd expect

A slow transfer can be bottlenecked by the source disk, destination disk, network, or CPU (for encryption/compression) — a lower-than-expected rate here is a starting point for investigation, not a diagnosis on its own.

Transfer rate (GB/s)

0.833

Useful for benchmarking a backup, migration, or file copy job's actual throughput.

What you entered

Data transferred (GB): 50Time elapsed (s): 60

1
Rate = data size ÷ time
50 GB ÷ 60 s= 0.8333 GB/s

Result

Transfer rate (GB/s): 0.833

Moving 50 GB in 60s is a transfer rate of 0.8333333333333334 GB/s.
