Volumio with Rpi4B and Allo DigiOne Signature

I’m really new to this. I have bought a Rpi4B with Allo DigiOne signature. I plan to run Volumio on it. This may be a dumb question but can I have music library on a hard drive and connect this drive directly to the Rpi?

Volumio should be able to play your music library from an external hard drive. Have you tried connecting it? Any problems?
