CUBASE 13 SRC and Drives

Anybody knows if Cubase 13’s sample rate conversion is as good as Voxengo 8brain pro ? any improvements from 9.5 version? and second thing I have some issue when I open a project from an external hard drive connected to a USB Hub ( peak and cache bars jump to red in seconds in performance audio graphic) is this true that the projects must be located in internal hard drive? because I ain’t got space for them. I am working with a mc studio M2 ultra with 1tb int drive and 64gb ram.
