VHDX Specification Available

In Windows Server 2012 / Windows 8 we have introduced a new virtual hard disk format called “VHDX”.  There are a number of advantages to this format:

• Support for greater than 2TB disks
• Better performance for dynamic and differencing disks
• Better handling of different disk sector sizes
• And more…

Last Friday we published the final specification for VHDX under our Open Specification Promise.  You can download it from here: https://www.microsoft.com/en-us/download/details.aspx?id=34750

Cheers,
Ben
