Tips & Best Practices

Use this conversion for planning and benchmarking between storage and optical communication systems
Remember that theoretical rates may not match real sustained speeds
Be aware of unit context differences when comparing burst transfer rates versus payload capacity
Apply the conversion mainly in legacy system and network capacity planning scenarios

Limitations

Max data rates are theoretical and might not reflect actual sustained performance
Units involve megabytes per second versus megabits per second, so conversions assume consistent context
This conversion tool is best suited to legacy equipment and telecom planning rather than direct data transfer equivalency
