Strongspace is a basic online storage service that provides a secure area to store all of your important files. A feature that sets Strongspace apart from the competition is you can have multiple users on one account.

This Internet storage service allows you to create multiple directories in your account, similar to what you could do on a hard drive. You can see all of your directories and files on your computer so you can choose the files you want to upload.

You can access your files from anywhere and share your files with anyone who has access to the Internet.

All of your files are secure—Strongspace uses SSL encryption and your files are transferred through a secure, encrypted connection. Additionally, your account is password protected.

Strongspace is more expensive than some of the other services in this review. Their accounts begin at $15 a month, for 5 GB of space and go up to $100 a month for 100 GB of storage space.

The interface is well designed and the service is easy to use. You can learn about how to use the features through a user guide, tutorial and a user forum. You can contact customer support through email if you have further questions.
