Partition Usb Key

[leprive]

Hello,
Sorry if this has been asked before, could not find it.
I'm using recalbox on my pc with a bootable usb key. This is fantastic.
It is using my PC'w wifi to access the network.
I find it a pain to transfer my roms through Wifi, I was wondering if the following was possible : partition the usb key, save 8Go to install the system and having the rest as a data partition with just the roms.

-If it is posible would it affect negatively the performances?
-I'm using osx do you know how to partition a usb key easily?
-What format should I use for the data partition?

Thx a lot for your answers

@leprive afaik, not possible. I‘d suggest copying everything (roms and bios stuff I mean) to an usb stick and plug it in another port and use the file manager in kodi to transfer them to recalbox.

Ok Thanks for this answer. This is a good trick never thought of that.
I might even not need the second usb key as kodi has access to the harddrive on the pc, that also coutains the rom.
