Microsoft beefed up its OneDrive (7 GB free; $25 per year for 50 GB) file-synchronization service when Google Drive (15 GB free; $2 per month for 100 GB; $10 per month for 1 TB) launched, and critics say the improvements -- which include PC and Mac clients, and an increased maximum file upload size of 2 GB -- make it a very compelling choice for people looking to share data among several computers, Windows Phones and/or iOS devices.
Built into Windows 8.1. Microsoft revamped its SkyDrive cloud storage service and renamed it OneDrive. Reviewers love OneDrive's clean design, which mimics the seamless interface in Dropbox (2 GB free; $10 per month for 100 GB) -- a strong competitor when it comes to file-syncing services. Dragging and dropping a file into the OneDrive folder on your PC or Mac makes it available almost immediately through the web interface or on other OneDrive-enabled devices, though file sizes are limited to 2 GB. OneDrive saves your last 25 revisions for every file stored. OneDrive is built into Windows 8.1 devices, but offers syncing and access for PCs, Macs, Android, iOS and Windows Phone. It doesn't work on Windows XP or Linux systems, however. It's worth noting that Microsoft no longer provides support for XP.ProsIntegrated with Windows 8.1 and apps, Intuitive, easy-to-use interface, Excellent for storing photosConsNo Windows XP or Linux support, Privacy concerns
