Extreme 500 w/ Chromebook

I can’t find any info on using my new SanDisk SSD with my Chromebook. SanDisk seems to have avoided providing software and instructions for us Chromebook users even though this SSD does work on Chromebook? I’d like to sync my sd card to this SSD for backup drone videos, is there a good sync app that will work with my newer Chromebook Flip, something easy for me to use?

Otherwise, I have the option of using my new iPad.  I have very little experience with Apple… where’s a good basic tuitorial on how to sync up the SSD with my sd card via iPad?
