1. Dropbox – Free up to 2GB (Referral bonus up to 10GB)
Dropbox is my personal favorite. It’s easy to setup, use, and access from almost any device with an internet connection. You can even mark favorite files for offline access. It installs as a folder on your computer that will automatically sync anything placed in it. You can then access that folder from their website or any other device you’ve installed the app. Another key feature is that you can share a folder with other users for synchronized collaboration.
2. Box.net – Free up to 1GB
Box.net is a leading enterprise class cloud storage solution. The Personal account enables you to sync files up to 25MB; whereas, the Business and Enterprise plans have advanced features for increased security, administrative controls, and integrations.
3. Google Docs– Free up to 7GB+ (shared with Gmail)I view Google Docs as a stepping stone into cloud storage. Although it’s a useful tool for sharing and collaborating, the web interface doesn’t yet stand up against desktop applications. For basic documents it’s a great free tool except for the restrictive size limitations.
4. Live Mesh– Free up to 5GBLive Mesh is Microsoft’s consumer level cloud solution. It’s called Mesh because it integrates beta versions of Messenger, Photo Gallery, Mail, Movie Maker, Writer, Family Safety, and Sync, plus Bing Bar and Messenger Companion. This feature rich service is undoubtedly going to be very popular.
5. ZumoDrive – Free up to 2GB
ZumoDrive is very similar to Dropbox in that it creates a new drive on your computer that is automatically synced with any connected device. The service is easy to setup and enables you to access your documents and multimedia content on netbooks and iPhones.
Bonus: JungleDisk– $2 per month + storage feesJungleDisk gets an honorable mention because it’s a little different from the other services. It’s a subsidiary of Rackspace that provides the front end software to create your own cloud storage. It’s tailored for business and enterprise users as it enables you to pay a relatively low monthly fee to JungleDisk and receive storage from Amazon S3 or Rackspace with pay-as-you-go pricing models. Advantage, you don’t get locked into a tiered pricing model, you only pay for the storage you use.
