Dual Boot Question - Can I share data drive(s)

Im attempting to build a dual boot system out of an HP Z220 CMT. Actually I have it up and running as a dual boot right now with macOS on a 500gb SSD and Win10Pro on a 2TB spinning disk. What I want to do is have bot OS installs on separate 500gb SSDs and then put all my data on spinning disks. Ideally I would like to share one disk since 99% of what I would put on there would be cross platform - images, videos, documents. Would I be better off partitioning or running two separate data drives?

Is this possible?

Is it advisable?

Thanks in advance
