The online cloud storage war has just exploded with the introduction of Google Drive earlier today. With Google Drive, now all major mobile operating system providers have some form of proprietary cloud storage solution including SkyDrive for Windows Phone 7 and iCloud for iOS along with several others like Dropbox, Box and SugarSync.

Both iCloud and Google Drive provide users with 5GB storage space for free whereas SkyDrive provides users with 7GB free space out of the box. SkyDrive initially started out with 25GB free space, but it has now cut down the storage to 7GB. However, if you have been an old user of SkyDrive, you will still be able to claim 25GB of free space.

To reclaim your 25GB of free space in SkyDrive, you will have to login to your account in your browser. Once you do that, you will see a link on the top saying; SkyDrive’s free storage is changing – claim your free 25GB.

Clicking on the link will take you to the manage storage page where you will be given an option to upgrade your storage. Just click on the “Free upgrade” button to increase your storage to 25GB. This option will only be available for a limited time to users who have already used Windows Live SkyDrive in the past. New users will only receive 7GB of free online storage space.

If you are unable to get 25GB in SkyDrive, there are still several other options available including free 50GB space from Box if you are an Android user and up-to 18GB storage in Dropbox from referrals and free space.
