SFS isn't something that can increase XSX's uncompressed speed beyond what is already specified. Also, texture compression is primarily handled by BCPack.Wrong. SFS apply WITH 4.8-6gb figure of the effective speed of the XSX IO.
This means that if a scene needs 12-15gb of texture data it can be loaded in about 1 sec using the AVERAGE numbers provided by Microsoft. (4.8gb/sec ucompressed x 2.5 SFS)
It doesn't make the IO go above it's weight. But the textures needed are more effectively transfered with SFS.
All these techniques contribute to the 4.8 Gb/s uncompressed speed which is the average / most common. It can be pushed to up to 6 Gb/s if everything is optimized perfectly, which is the theoretical peak. PS5's theoretical peak is 22 Gb/s -- but that would be extremely rare, especially without Oodle.
