ADrive Version 1.0 Release Tonight

The ADrive Team has been working around the clock to release our version 1.0. Our scheduled release will take place tonight. Once again, we will need your cooperation while we upgrade our systems, as we will require another maintenance window of a few hours starting on July 1, 2008 at 10pm PDT. During this time, you will not be able to access your ADrive account. Once we have completed our upgrade, ADrive will be back online and you can continue to enjoy all the ADrive features.

The release of ADrive version 1.0 will not affect your current account or files in anyway; users will still enjoy 50GB of free online storage. As an added feature, all users will be able to download the ADrive Backup Client to their desktop for free. Users will also have the option of upgrading to either our Signature or Premium accounts. These paid plans offer SSL encryption for all data transfers, WebDAV, multiple concurrent sessions, and 24/7 support among other features.

So my friends over at adrive launched Version 1.0 today and damn, there are some cool features. My favorite being webdav, encryption, and a desktop app. And, as always, 50Gb of online storage for free is insane!
