Windows Server 8 Hyper-V VHDX improvements


With Windows 8 and Windows Server 8 Microsoft released a new file format for Virtual Hard Disk called VHDX.

The VHD format, which was availible since 2005 (Microsoft Virtual PC) and is now used by Microsoft Hyper-V and other Hypervisor, had some limitations.

The latest version of the VHD format was limited to 2TB of size and a block file size of 512bytes.

Now with VHDX Microsoft kills this limitations and brings some other improvements:

  • Supports up to 16TB size
  • Supports larger block file size
  • improved performance
  • improved corruption resistance

At this time you can use the VHDX format only with Windows 8 and Windows Server 8. But you can convert VHDs the VHDX format and VHDX disks back to VHDs.
