Topic: Does MacOS High Sierra APFS only support SSDs?

[krishna88]

macOS High Sierra has been released on septemeber 25 2017,  One of the big features of High Sierra is the introduction of APFS (Apple new filesystem) which is targeting Flash/SSD storage. As per the support note, installing High Sierra on a Mac with a Flash/SSD will cause the conversion from HFS to APFS is automatic and cannot be opt'ed out of.

Macs with regular HDDs and Fusion drive are exempt from the automatic conversion, but it isn't clear if APFS will support those drives (initial thinking is that it wouldn't)..

My Question is does MacOS High Sierra APFS only support SSDs?

I doubt that, since you can swap an SSD with an HDD and low-level clone the drives, etc.
