    Welcome to the Microsoft Q&A (Preview) platform.
    Happy to answer your questions.

    Each data disk can be up to 32,767 GiB. The number of data disks you can use depends on the size of the virtual machine. For details, see Sizes for Virtual Machines.
    Azure Managed Disks are the recommended disk storage offerings for use with Azure Virtual Machines for persistent storage of data. You can use multiple Managed Disks with each Virtual Machine. Managed Disks offer two types of durable storage options: Premium and Standard Managed Disks. For pricing information, see Managed Disks Pricing.
    Azure storage accounts can also provide storage for the operating system disk and any data disks. Each disk is a .vhd file stored as a page blob. For pricing details, see Storage Pricing Details.

    The max number disks depends on the size you choose. For example you can get more insights about all available sizes of VM's and supported number of NIC's and Disks for E4 V3 size vms at

    Hi @EnterpriseArchitect ,

    the max number of data disks attached to a VM depends on the VM SKU.
    Please take look here:
    On the left side of the website you can select different VM SKU series. From there you will find a tables with all the information related to the VM SKUs like vCPU, RAM max disks and max NICs.

    As the original question is already answered it might make sense to open a new question next time ;-)
