In the past few weeks, three big competitors have arisen in the realm of online storage for Windows users: Dropbox, Microsoft SkyDrive, and Google Drive. On the surface, each service has similar offerings. But depending on how you plan to use your online storage, one may be a better fit than the others.
What follows is a review based on features and usage scenarios.
First of all, it is important to envision what you'll use online storage for. Here are the main uses:
Cloud-based File Backup - Personal file backup is the ability to keep your important files in a folder that is connected to the cloud and continuously backed-up and synchronized. That way if your local hard drive crashes, you have an online backup.
Access Files From Multiple Devices - Since everything is continually updated and synchronized in the the cloud, your files can be accessed in their most up-to-date states via a web browser. That means they're available on your tablet, mobile or PC.
Create and Edit Documents - Google Drive and Microsoft SkyDrive let you create and edit docs in your browser. These docs are compatible or exportable to the most common word processors for eventual printing. Since everything is synced, you can edit docs on all of your devices--start one on your PC at home, finish it on your laptop in the airport. And you can even collaborate on these docs by giving people access to them in the cloud. You could, for example, work as a team editing an essay in the cloud, and each member of the team would see the updates made almost immediately.
Share Photos and Galleries - You can upload your digital photos to these services and they'll display in gallery formats. You can share these photos with other users in the cloud.
File Sharing - You can set up sharing for folders and, as the creator, you decide who has access to to those folders. This is a good alternative to emailing attachments because of auto-syncing and the fact that people do not have to download attachments (files are shared, instead, via links).
Now that we have a good understanding of the basic uses for online storage, we can compare/contrast Google Drive, SkyDrive, and Dropbox.
Dropbox:
Storage GB - You get 2GB of free storage and additional storage of 500 MB per referral--up to 18GB. Additional storage can also be purchased on yearly or monthly rates. Pro 50 is 50 GB for $9.99 a month or $99 a year. Pro 100 is 100 GB for $19.99 a month or $199 a year.
Where Dropbox is weakest is that it doesn't allow document creation or editing. It does, however, offer a nifty photo gallery, which can be easily shared with other Dropbox users, via email, and with friends on Facebook and Twitter.
It's available on Windows, Mac, Linux and mobile, including Android, BlackBerry, and iOS.
Microsoft SkyDrive:
Storage GB: 7GB for free upon signing up and current users get a 25GB loyalty reward.
Paid storage (annually): 20 GB for $10; 50 GB $25; 100 GB $50.
Microsoft has a very good photo gallery viewer which can easily be used to share photos within SkyDrive, email, or on social networks.
Create and edit documents using Office Web Apps. This works seamlessly with Microsoft products.
Another unique feature is that you can remotely access desktops that have the SkyDrive PC client installed. Using a feature called "fetch."
Synchronization with other devices and platforms is very good too. It works on Windows, Mac, iOS, Windows Mobile and Android via third-party apps
Google Drive
Storage GB: You get 5GB for free fir signing up.
Paid Storage: 25GB $30 a year; 100 GB for $60 a year
Google Drive's weak spot is that it doesn't allow photo sharing. You must do this through Picassa and/or Google+. Also, you can't share with Facebook.
Basically this is the next generation of Google Docs, which is going to help Google because Docs is already very popular and it fits so snugly in with the rest of Google's products--search, Gmail, Chrome etc.
Works with Mac, Windows (with Windows app), and Android.
