@Samy Abdul Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
Data copy really depends on size of the data, type of the data, and network bandwidth.
When you create a Data Box order, pricing is displayed. Also you can refer to the Data Box pricing page: https://azure.microsoft.com/en-us/pricing/details/databox/
Data transfer rates can vary greatly - it depends on the file sizes/amount of files being transferred/network bandwidth. For some jobs it can take a few days and for some it can take a few weeks. Normally you will get a good idea of how long it will take to upload on the other end because the upload takes about the same amount of time as the initial download onto the boxes.
Hope this helps!
Kindly let us know if the above helps or you need further assistance on this issue.
