However, if you expect you might want to move a VM to a previous version of Windows Server or Azure, it could be easier to keep your VHD files.Microsofts virtual hard disk format, VHDX, has some important advantages over the legacy VHD format, as this VHD vs.Windows Server 2012 supports the new format but also lets Hyper-V administrators use the legacy VHD format.With two virtual hard disk formats to choose from, lets take a minute to talk about VHD vs.
VHDX. Before Windows Server 2012, Hyper-V virtual hard disks had a 2 TB limit. The advantages of VHDX arent limited to improved capacity, however; VHDX files were designed to work with todays modern hardware and have a 4 KB logical sector size that improves performance compared with VHD files. Larger block sizes for dynamic and differencing disks, as well as the ability to store custom metadata, also give the new format the edge in the VHD vs. Hyper-V allows you to create 2 primary hard disk storage types, fixed or dynamic. Dynamic size drives are allocated with the minimum space needed and space is expanded as you write additional drive to the volume. There is performance loss on disk writes that require storage to be expanded. For example, if you create a dynamic volume with 10 GB and as you write data and use up the entire 10GB allocation then the volume needs to be expanded first then your data will be written to the volume. This expansion adds overhead and can slow down data writes by 25 or more. Since the file is preallocated on the Hyper-V host there is no loss in performance due to the need for expansion of space. ![]() In tests performed by others, they have seen negligible difference in overhead with Dynamic VHDX volumes when they expand to accommodate additional data. You can easily convert your VHD volumes to VHDX and vise visa. As always, make a backup and make sure you have enough time allocated for the conversion. The way it works is it will create a new VHDX disk and copy the data from the existing VHD to the new disk. After it copies the data, you have two disks such as original VHD disk and new VHDX disk exactly with the same content. Once you confirm the newly generated VHDX disk is fully functional, you can opt for deleting old original VHD disk. After selecting the disk which you want to convert, confirm it again. Press Next to select the name and location of the new VHDX file format. And to finish, it will start operation for creating new VHDX file. This makes an exact copy of VHD file format as a new VHDX file.
