Algoriddim external hard drive for iPad

I use the idj pro and djay app on my iPad to Dj in local bars and pubs. I only have a 16gb iPad because I didn’t expect to Dj on a iPad if I’m honest. The problem I’m having is I don’t have enough memory to store all the genres of music I’d like to play and also I don’t have any memory to have any other app on my iPad besides the djay app. Maybe a algoriddim external hard drive that can store my music, kinda like the wi-drive but that works directly with the djay app
