Practicality - Practical features make uploading, storing, accessing and sharing your files easy. Online storage services should offer remote access, public and private file sharing, scheduled backup and a drag–and–drop window.
Security - Security is very important when storing files. Web storage services should offer encrypted file transfer and password protection.
Affordability - The top online storage services offer a lot of storage space for a reasonable price, free trial accounts and don’t charge setup fees.
Intuitiveness - Online storage services should be user–friendly and not require a computer engineering degree in order to upload and access files.
Support - Good help and support is necessary with any service. Online storage services should provide self–help through FAQs, user manuals and tutorials. They should also provide customer support through email, phone or online chat.
