Which external SSD for music streaming?

@stievus Then there's always the possibility that a particular album or artist that you love suddenly becomes unavailable on Quboz or whatever your current streaming platform of choice. Given the minimal cost of storage, I feel it doesn't hurt to at least have your CD collection and any other digital audio files you may have on an SSD with an HDD backup.

@roccity True; some titles I played a lot already disappeared (while they still are in Spotify). Problem is, you never know in advance which ones will disappear, and buying everything I like will be a fortune.

a member here with significant streaming expertise (can't remember who) recommended the Samsung T7 a couple years ago--i bought two on that recommendation although my streamer is also a server with its own internal storage so i just use them for backup--but i can designate the streamer to use them (which i did at first) and they worked smoothly.  Someone above also mentioned.

The external Samsung drives should be fine, but are more costly than Samsung SATA drives in a third party external USB case. A QVO 2.5” 4 TB drive in a competent USB 3.0/3.1 case might bring a better cost-per-GB ratio and shouldn’t sacrifice anything for audio data purposes.

I only mention this because comparative price point seems a consideration of OP.

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.
