The new, larger Azure IaaS VM disks: Partners answer, is bigger necessarily better?

This article has been updated to include additional comments from hosting partners.

Microsoft last week announced that Microsoft Azure is increasing the maximum size and performance of Azure disks. In a blog post by Azure Storage Program Manager Yuemin Lu, the company announced the increase for both Premium and Standard storage, extending the maximum size of the disks from 1,024 GB to 4,095 GB (about 4 TB) - in theory, enabling customers to add 4x the disk storage capacity per VM.

So for example, on one GS5 VM using 64 of the 4 TB disks, customers can provision up to a total of 256 TB of storage. "As a result, customers no longer need to scale up to multiple VMs or stripe multiple disks to provision larger disk capacity," says Lu.
