Internal Drive
The Xbox One X's internal hard drive is a 5400 RPM spinnner, SATA III drive with a maximum sequential read speed of around 150 MB/s (540-559 MB/s in benchmarks) and a write speed of approximately 453 MB/s. While the SATA III interface can technically support faster speeds up to 6 Gbit/s, the 5400 RPM rotational speed of the hard drive is the primary bottleneck for performance. USB 3.0 External SSDs can theoritcall xfr at 5 GBPS: Connecting an external USB 3.0 SSD to an Xbox One X can significantly reduce game load times because SSDs have much faster read/write speeds than the internal HDD, often reaching 500–550 MB/s for the SSD itself.
So games could play better over External HD if it's an SSD.
Comparisons
Xbox Series X obviously is the most powerful all around, however.
