For me, my less than one year old USB Pioneer BDR-XS07S disc drive doesn't communicate properly with Apple Music through the Belkin hub I purchased from Apple when I bought my prior M1 Mini. My desire to solve that issue meant that I would have to roll the dice and buy another hub of some kind.A great plan!
I was doing something similar, but for $180 was I was able to switch to an internal 2TB drive and skip the dock/external NVMe part altogether
Worth considering
(Prices have gone up slightly and I used a coupon to get to $180 -- still only $215 right now though -- great value)

Just upgrading the internal SSD would not have addressed the drive issue.
