I have 2 windows 2008R2 virtual machines configured the same. I'm setting up a 2nd virtual disk drive on both of them which are on the same LUN.

On vm1 I did
create partition primary align=64

On vm2 I did
create partition primary align=1024

Then on both vm's
format fs=ntfs unit=64K label="Data"

Vm1 is formatting its volume substantially faster than vm2. Vm1's formatting was started first.

Is it reasonable to deduce the alignment of 1024 is negatively affecting the format speed?

Or is it more likely a vm is getting better priority somehow, or some other factor I'm overlooking?
