The Bandwidth Calculator is a bandwidth calculator and data solver for the Mac. (Iphone and IPad versions also!)
The calculator features the ability to calculate the time needed to transfer data across a given data pipe as well as a bitrate solver. In many cases, you may have a backup window and need to know how big a data pipe to purchase to meet certain objectives. The included solver will help you with this. Put it any size data to be transferred and the time period in days, hours or minutes and the solver will calculate the size pipe you need in Mbit/s.
Additional features include:
*Pipe efficiency variables
*Protocol efficiency variables
All in all, the The Bandwidth Calculator is your one stop shop for calculating disaster recovery scenarios, backup scenarios, or a great tool if you just need to know how long it takes to copy data from your hard drive to a server.
