Hi Sven,
The default reflects a recommendation and is based upon the guest OS you select. For some guest OSes, we recommend virtual SATA HDD and/or CD so we create those by default, and for others we still recommend SCSI or even IDE. Our recommendation is driven by the expected level of supportability of the guest OS on each of the available controllers. (Some guests have defective drivers for some controllers, or have slow drivers, or simply lack the needed drivers...)
The virtual SATA implementation in Fusion 6 (and Workstation 10) has been very thoroughly tested and is certainly not experimental.
That said, please do let us know if you encounter any problems with it! Image may be NSFW.
Clik here to view.
Cheers,
