Can I create Windows Azure drive as 1T size straight way

Question

The max size for Windows Azure drive is 1T

M$ only charged for the data in it, not for the size

My question is: why not just create an Azure Drive at size 1T

Answer 1

I often do that when creating an Azure Drive: allocating a maximum size drive of 1TB. No discernable penalty. The only advantage to setting a smaller size: protecting yourself against cost overruns. There might be a possibility it takes longer to initialize a 1TB drive, but I haven't measured it.
