Computer storage has grown starting from about 1.5 MB disk, 512 MB flashdisk, 10 GB HDD, until now 1 or more TB storages.
The growing of storage is depended on human behaviour needs. For example, a lot of people move from HD video to 4K video format, there is also an increasing of mp3 collections, books, documents, and other files.
These situations are the evidence that we need a big storage, but have we ever thought that actually we just interact with some gigabytes or megabytes on daily basis?
So, why do you need the big storage? why do you save all of your files on your Computer?
