When creating virtual hard drives, it would be nice if a certain amount of disk space can be specified to be preallocated or initialized so that initial disk utilization would be a bit faster.

I noticed on dynamically allocated virtual hard drives, installing any OS takes longer than if I were using fixed size virtual hard drive.

This may no longer be true when using SSDs, but it would be a few more years before SSDs are as affordable and high capacity as today's HDDs.

So if I know that an OS install would take up 3.5G, I would create a 20GB dynamically allocated hard drive but set about 5GB of pre initialized space.
