Sony's iLink is simply a firewire connector that does not provide power to
the device. That's the only difference between the 4 and 6 pin connectors.
6pin can provide power. Things like camcorders require separate power
supplies anyway so effectively there is no difference and data transfers at
up to 400 over either. 9pin is another matter. That provides for a
firewire transfer speed up to 800. 9pin and 6pin connectors are compatible
but 9pin and 4pin connectors are not.
