Is there any evidence of how fast local Azure VM drives are?

I am experimenting with OnStart()in my role as Azure using small instances. It turns out that it takes about two minutes to unzip a 400 megabyte ZIP file located in the "local storage" on drive D into a folder on drive E.

Although I may have to do it differently, I can’t find any data on how fast local drives on Azure VM are.

Are there any test results on how fast local Azure VM drives are?

I just made a comparison of disk performance between Azure and Amazon EC2. You can read it here , although you probably want to translate it from Norwegian :-)

The following HD Tune screenshots are interesting, however.

First, a small instance on Amazon EC2 running Windows Server 2008:

Next, a small instance on Azure running Windows Server 2012:

This is not a fair comparison, as some of the differences may be due to the lack of Windows 2012 drivers, but you may still find this useful.

As Sandrino noted, although small instances in Azure only get “moderate” I / O performance, and this may be an argument in favor of Amazon.
