If you're using softRAID via md, you can run RAID-5 on almost any block 
device that you have 3 or more of.  ISTR that someone did RAID-5 on a 
bunch of USB floppy drives in the 2000s as a proof of concept and/or 
silly demonstration.  Can't find the article that I originally read[0], 
but 
https://fitzcarraldoblog.wordpress.com/2019/10/17/creating-a-raid-of-usb-pendrives-in-linux/ 
shows a similar procedure using RAID-10 instead of RAID-5.  By reading 
the man page for mdadm and the HOWTO for softRAID ( 
https://raid.wiki.kernel.org/index.php/Linux_Raid ) and understanding 
things, I think you might be able to use that article to do something 
similar.

[0] Both google and duckduckgo are returning useless results more often 
than not these days.  I think that search engines were actually *better* 
at returning useful data in 2010 than they are now.  I blame 
advertisers.
