Are there specific NAS requirements for streaming?

I am planning on getting a Cambridge Audio streamer and plan to store my music on a NAS. Reading on the Roon website (which I do not plan to use), I see there are recommendations regarding processors, memory and at least a SSD for the Roon server to reside on. If I want to use Apple Music and Airplay with controls via an iPad or iPhone, are there specific NAS requirements?  I see the current Synology and QNAP NAS units are recognized as good options. I have a old Drobo FS that I can use but don’t know if this would be optimal. This would save money but. I noticed when I used it for storing photos for my Lightroom processing , it was quite slow.
