3. SkyDrive:
Free Storage Available: 7GB
Extra Storage:  20GB for $10 per year
                             50GB for $25 per year
                             100GB for $50 per year

An integral part of Microsoft, SkyDrive provides storage services for both Windows and Mac operating systems. Users can upload individual files, where bulk uploading is not supported through browsers. The user interface is considered to be the most pitiable version among storage services, as the option of sharing files is limited to its website. But still SkyDrive provides the option of direct uploading of files and documents from Microsoft’s Office Web apps and can be distributed directly to users in Hotmail contact lists.

4. SugarSync
Free Storage Available: 5GB
Extra Storage: 30GB for $4.99 per year
                            60GB for $9.99 per year
                          

A surprise contender to feature this list, SugarSync is considered as the black horse in online storage services. SugarSync outstands with its ‘Magic Briefcase’ option; that is anything placed there is automatically synced across all devices registered to the user account. The ‘Web Archive’ is another option that stores files, but it disallows user’s to share the same file if the originals are changed. The client interface is also considered as one of the best, as it provides the overall view of files synced across all the devices in the cloud.
