LAN Data Rate Units
There is standard 100 Mbps ethernet, which is what most people have at home. 100 Mbps is 100 megabits per second. That is translated into 12.5 megabytes per second (MBps or MB/s). It's much easier to convert to MBs since that is something we are all familiar with rather than bits.
Ideally, you can transfer 1 GB in eight seconds over a 1 Gbps network. If you scale that up to a huge dataset (for example, 100 TB), the transfer time is 12 days. Transferring huge datasets can test the limits of your infrastructure and potentially cause problems for your business.
