In present days, computers and laptops has become an inseparable part of our busy life. One of the commonly used device for data transfers is Universal Serial Bus(USB) flash drives. Due to emerging technology, USB devices are shrinking in size day by day, but not the equipment’s which is required to access them. Data transfer using portable devices is the most important factor of today's scenario. Data transfer between two pen drives is generally done using laptops or desktops. But it is not always possible to carry such a large size device to the particular location. So, to overcome this problem, we are designing a hardware which is more compact to carry anywhere. With the help of this project we cannot only transfer the data between devices but also, we can see the transfer of the particular file which we want to send by using LCD display. This system pen drive to pen drive data transfer without PC is done by using Raspberry Pi. The pen drives are connected to USB module through USB hub, the communication between two pen drives is done by using Raspberry Pi. Using this System, the data transfer can be done from any place in world.
