Here Are Four Options for Free Storage in the Cloud:
DropBox
Google's DropBox offers 2GB of free online storage. Other options include 50GB for $9.99 per month, or 100GB for $19.99 per month. When put your files in a DropBox folder in one computer, they're uploaded to the site's secure servers. Google Docs has a 250MB file size limit, but DropBox has no such limitation. You can access your files from other computers (Windows, Mac, or Linux) or mobile devices that run DropBox too.
Box.Net
Targeted at the corporate crowd, Box.Net is a little less generous in the storage department.
The site's free option provides 1GB of online storage with a 25MB file-size limit. For $10 per month, you get 5GB of storage and a 1GB file size limit. The $15 per month plan includes 10GB of storage, with the same 1-gig file cutoff. Pricier plans for enterprise customers (with unlimited storage) are available too.
