No clue, I'd just use the SATA3 option... 750MB/s peak throughput seems sufficient... Obviously that depends on the max the SATA SSD can dish out...
You've got options.
SATA3
USB 3.0+
PCI-E NVMe card
I just came to make USB feel better about itself.
USB 3.0 is kinda negligible vs SATA depending whether your saturating tue bus with anything else.
USB 3.1 has considerably higher throughput, although I can't speak to any latency differences between it and SATA. Granted, USB and SATA are...
I also bought the One S for Blu-ray, and wanted the Series X for the same thing and my library of disc games. The Series S is borderline useless to me, and underpowered IMO.
That sucks
Use these links or carefully search directly and click that "add button" directly.
When I click on the Forza deal it takes me to a more expensive one, but if I click add it does the 350 one. Some are also local pick-up only so that's annoying...
My daughter and I were pleased that this Series X deal allowed for good performance in Goat Simulatior 3, which we beat last night.
Excellent find.
