Legacy SanDisk Products Extreme Pro Internal SSD

I am about to start to use Extreme PRO 128GB USB 3.0 Flash Drive
I intend to use it to backup files both in iMac High Sierra 10.13 and also on Windows 10 Home 64 bit computers.
Could You please give Me detailed information of how to
a. Initiallize pen drive (if necessary)
b. create 2 partitions: one to use with iMac, and another one to use with Windows 10. (please also show me how to assign sizes to each individual partition. Is there a maximum number of partitions allowed to be created? Is there a minimum size for any partition?)
c Which OS should i be creating partitions with (or from)?
d. If they are encryptable please show Me how to do that.

I would much appreciate your help with this matter.

Thank You kindly.
Carlos V.

This video shows how to create both a primary time machine compatible partition and exfat secondary partition compatible with windows. Its very simple, and would be done from the mac.

Partition limits are fuzzy, there is what they claim as limit and what works, at least a dozen, windows claims 128, some claim 16 is buggy on mac, but in theory no limit for HFS, but in any case way more than any user will practically need.
