Overview ____________________ This Raspberry pi project is innovated to ease data transfer b/w hard-disk to many no of devices at a time. Lets get overview of this project through an example. Assume we are on a class of 60 students and teachers are willing to gave us notes which is about 20 to 30 GB in size. Then how they will provide us notes. First case:- They might gave their pen-drive to each and every student and wait till all students finished coping it. But this whole process consume lots of time. Second case:- Sir may upload this whole 30 GB file to Google drive But wait Google provide only 15 GB of free space per account. So this idea fails to. To solve this problem I made a device using raspberry pi.
