To Jack - Yea those are some pretty cool features. I personally know the guys that made adrive.com so of course I am biased to their site. However, after checking out myotherdrive.com I see some drawbacks that adrive.com addresses. First and foremost, adrive.com offers 50gb of free online storage whereas your site only offers 5gb. I think that alone makes adrive worth the extra clicks to transfer files between users. the AES encryption is fucking awesome though, I'm going to recommend to my friends to implement that for adrive. In addition, adrive offers a few other features which I don't see on your site. I may be misinformed, but adrive offers a desktop application to upload files to the website and webdav, which I don't see on yours. Regardless, thanks for the input, I definitely love hearing about new free data storage solutions.

I prefer http://www.MyOtherDrive.com because they have not only the best online backup, but they also have the best file sharing site. No other site I have seen offers their "Copy To My Drive" feature. One user can upload a file and others can copy it to their account without upload / download - very cool.

Their online backup supports unattended backup and AES 128-bit encryption. They have secure links - no more emailing big file attachments (and getting them blocked). These secure links require username / password to open - very cool.

eBucket WebDrive offers a one-of-kind 3D online file storage at a fraction of the cost. Unlimited storage space. Secure data transfer. Multi-file uploads&downloads up to 5GB per file! Drag&Drop file manager. Transfer queue manager. MP3 & M4A (AAC) Music Player, Image Viewer,
HD Video Player. Reliable. Scalable. Secure. Powered by Amazon Simple Storage.

50GB is still the most I've seen offered. Thanks for letting me know about ADrive.
