Has anyone done IOx on Catalyst 9K switches? Question about USB options.

Has anyone tried out the IOx Application Hosting on the Cisco Catalyst 9000 series (9300 in my case).

I was interested in giving this specific example a try in my lab at work as a i have an available 9300 -

I'm not a bit hosting/container expert but I can see an advantage in generating traffic like this direct from a switch using iperf.

But just as i had a USB stick ready to go I stumbled upon this note:

"Internal flash and front panel usb (usbflash0:) do not support for application hosting."

So reading into this, officially, you have to get a Cisco 120GB-SDD to use this feature:

Now I get how this works. If i don't use the official, expensive (probably, didn't bother checking) Cisco branded drive its unsupported. But wondering if anyone has got this working with a thumbdrive in usbflash0 (front panel) or if a regular SSD will work in that usbflash1 (back port). Before I go messing around with drives and wasting a bunch of time I was hoping the community might have some advice.

A broader questions would be what checks could a Cisco Switch do to determine whether it is an official Cisco USB SSD and what is the recommended drive format for a Cisco switch these days?
