At its I/O conference, Google announced new version of Drive and Google Drive for work. Google has also improved other Google Apps for business with new security features.
Google Drive for Work offers unlimited storage only for $10 per month. Maximum file size for upload limit has also been increased to 5 terabytes. But I do not think that any one is going to upload a 5 terabyte file to Drive.
Google also announced that it will now encrypt Drive, Gmail and Calendar data at data centers. Google already encrypts data in transfer between servers to devices.
Google has also announced Audit API to provide Drive statistics. Companies can use this api to create custom dashboard and develop their own policies.
Mobile apps of Google Drive for iOS and Android have also been refreshed to offer cleaner interfaces and faster performance.
Google also confirmed that Google Drive has 190 million 30-days active users.
