>for all other devices Yes, the solid state storage for which it is designed. The Fusion Drive by definition includes rotating media and compounds this problem by involving 2 devices in a common logical storage device. The APFS support for Fusion Drives was pulled from High Sierra for reasons that were never explained so there were apparently issues, and without knowing what those were it is impossible to evaluate how likely it is that these were all resolved now.
