Windows Live SkyDrive is about to get a considerable boost to the free storage space allowed with the service. Liveside reported earlier today that the popular Microsoft service will get a storage upgrade, allowing unlimited storage space for both Office documents and photos, leaving the original 25 GB for any other files you wish to store in the cloud.

25 GB of free storage for everything else

This increase will be added to Windows Live SkyDrive Wave 5 sometime in the near future, and will be quite considerable when you take into account the 70 million people that use the service today. There are also plans to expand the realms of SkyDrive, as Microsoft is currently developing native clients for Windows, Mac OS X, iOS and Android along with the client embedded into Windows Phone 7.

Microsoft has been good at consistently increasing the space allowed for SkyDrive users. When the service launched in 2007 it only offered 500 MB, which increased to 5 GB the next year. With the launch of SkyDrive Wave 3 in late 2008 this got a huge increase to the current 25 GB – more than Google offers for free across their services and more than Dropbox’s 2 GB. With unlimited storage available for documents and photos, SkyDrive should cement itself in the top spot of providing cloud storage.
