I have a jbod of 12 drives and each one is 16TB for a total of 192TB.

I want to create a single volume of out these drives so I tried using windows storage space but it seems that it won't let me create a volume more than 63TB.

After googling it seems that this is a limit on windows 10 pro.

What are my options of overcoming this limit? Do I need to upgrade to window server or workstation or is there a way to achieve a single volume in windows 10 pro as well?

    What size are the clusters? Looks like they'll need to be 64kb

    Hi,
    The volume limit is determined based on the file system and cluster size.
