Have had no problems with corrupted files, dropped devices or not recognising devices.
It even recognises Ipod Nanos properly unlike the version of Poseidon I have.
That is only 3.8 though (I think) as support was stopped for Spider at that point.
I have no doubt Poseidon supports more though.
It does support floppy USB drives for instance.
The big difference is USB1 Versus USB2 I would say.
That is planned for Sirion I'm told.
