Whether you are at your desk in the office or on your phone sitting in an airport, accessing your files is important. 5+ years ago you would have been carrying around flash drives and other mediums to access your data on the go, but now we have access to the cloud. With a login and some quick swipes you can have access to all your data. But, which cloud storage service is the best? There are more than a handful of companies out there that offer some type of "free cloud storage!" With the added bonus of getting more storage by referring a friend or by sharing a social status. There are some the promise nothing but secure data access, some that offer access on any platform, some that offer terabytes of storage, and some that offer all three. With all the different offers out there, what service do you trust your data with?
