Space on Microsoft's OneDrive cloud storage service just got a lot cheaper. Microsoft has more than doubled the base storage from 7GB to 15GB, and it cut the prices of paid storage. 100GB has been slashed from $7.49 per month to $1.99. 200GB has gone from $11.49 a month to $3.99, meaning that, strangely, two 100GB subscriptions are slightly cheaper than one 200GB option.

The storage bundled with Office 365 has also been substantially upgraded. Office 365 Home, at $9.99 a month, Office 365 Personal, at $6.99 a month, and Office 365 University, at $79.99 for four years, will all come with 1TB of OneDrive space per user. The Office 365 Home subscription is good for up to five users, and as such it provides a total of 5TB.

Business users haven't been left out either. All business Office 365 schemes will now come with 1TB of OneDrive for Business per user. OneDrive for Business, though similarly named to OneDrive, is a very different service that's built on top of SharePoint.

For both home and business users, the new prices and sizes will go into effect next month.

The new pricing and allowances bring OneDrive in line with Google Drive. That too starts at 15GB for free, and it similarly costs $1.99 per month for 100GB. Google's pricing does get much cheaper if you buy more space, however; 1TB of Google Drive costs $9.99 a month.

The new OneDrive scheme is more competitive for business users; Google gives Google Apps Business and Education accounts 30GB of storage, compared to Microsoft's 1TB.
