Cloud Storage Review

StoreGate Review

Storage Features-

One GB of space is allowed in the free hosting service. Files that can be uploaded include music and documents. Files can be shared via a weblink to a folder, or they can also be shared via facebook, twitter, or a blog. Another unique feature of storegate is its ability to back up your phone or mobile device.

The paid service of storegate offers you 5GB of data for $7.99. This is much more expensive than competing storage companies, and for this reason I would probably choose them over storegate for paid file hosting. However, the ability to back up a mobile device is very useful, and for that reason you could consider it’s use.
