Microsoft Azure: Using SSDs in Azure Virtual Machines and Azure Cloud Services

Recently Microsoft released a new set of VM sizes for Microsoft Azure. What makes these new VMs special is that they not only offer faster vCPUs (approximately 60% faster than the A series) and more memory (up to 112 GB), the new VM sizes also all have a local SSD disk (up to 800 GB) to enable much faster IO reads and writes.

If you are looking for even better performance, these are the VM sizes you need!
