And make sure you align your NTFS partition regardless off the underlying storage. Windows 2003 and before DONT do this by default, 7 and 2008 choose a default offset off 1Mb. But better check it in advance with diskpart. Lastly format your NTFS filesystem with an appropriate cluster size. Which needs to be determined on a case by case basis. Large video file are a different workload than an exchange server. I've got a set of thin provisioned vmdk's of varying size and cluster size. Which I can clone for new machines. This saves me the diskpart step, which you cannot run when installing windows.
