The SSD part was predominantly for hosting music production sample libraries and instrument data (so, lots of random small files), where quick random access over TBs of data is desirable. I've also got a few other use cases where having a lot of networked SSD storage is beneficial if not perhaps necessary (my RAW photo library in lightroom is another one fairly significant one that pops to mind).

For consumption media, that's 100% going on a slower pool of spinning disks, my plan is/was a mixed media setup
