Antwoord op "Compatibility 220v & 110v?"The Slim uses like the Fat an PSU with active PFC. And in all countries the same PSU is used. 110-240V AC 50 & 60 Hz. To make different PSUs for different countries is to expensive these days.
Antwoord op "SATA revision 2.0 or 3.0?"In fact, on 2.5 inch HDDs it makes no change at all. The drives are to slow to get the benefit of 300MB/s more than with 2.0. It only makes a change on SSDs, but I don't think that the slim comes with an (big) SSD. The maximum speed of HDDs is limited for 2.5 inch drives at about 200MB/s if buffered. So SATA 3.0 will not make the drive faster. For the PS4 Pro the effect is much bigger. The use of a SSD makes more sense.
