Microsoft will be introducing a new file system with Windows 8 Server, called ReFS, which is built on top of the existing NTFS, but will deliver new features for scale and prevent data corruption.

ReFS, short for Resilient File System, will initially debut with Windows 8 Server, but is expected to make its way through to Windows 8 client system to support the full feature set of Storage Spaces, which will allow users to create storage pools from multiple physical and virtual storage devices.
