Either you have enough bandwidth or you don't. Any USB 3.0 port will have plenty of bandwidth.
It's like those Internet providers who offer gigabit speeds (and more) to the house, when watching TV takes less than 10 MB.
Which external SSD for music streaming?
My new music streamer has a USB socket to connect an external Solid State Drive. I am thinking of getting one with 2 or 4 TB storage capacity to store my whole CD collection on it. What I don't know is how fast such an SSD needs to be. I was thinking of a Crucial X6 (up to 800 MB/s), or X9 (up to 1050MB/s). Or is any SSD fast enough to stream music smoothly? Thanks
