If you're using softRAID via md, you can run RAID-5 on almost any block <br>
device that you have 3 or more of. ISTR that someone did RAID-5 on a <br>
bunch of USB floppy drives in the 2000s as a proof of concept and/or <br>
silly demonstration. Can't find the article that I originally read[0], <br>
but <br>

shows a similar procedure using RAID-10 instead of RAID-5. By reading <br>
the man page for mdadm and the HOWTO for softRAID ( <br>
<a href="https://raid.wiki.kernel.org/index.php/Linux_Raid" rel="noreferrer" target="_blank">https://raid.wiki.kernel.org/index.php/Linux_Raid</a> ) and understanding <br>
things, I think you might be able to use that article to do something <br>
similar.<br>

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