Data we need to store is increacing drasticly. Although emerges the cloud technology, because of its security problems and dependence on the internet, we still need more portble hard disks to store data. Then the storage and arrangement of them becomes a problem.

 

Pilup is designed to solve this problem. They can be easily piled up to be tidy and use less space to store and transport.

 

Users can write words on them and the disks have different colours, supporting individuation and recognition.
