Have been doing a bit of shopping this weekend, just ordered a D-Link DNS-320 NAS and hard drives to go with. The NAS has a gigabit interface, and I have a gigabit switch, but my laptop only has a 100Mbits interface. So Im considering buying a Cardbus (PCMCIA) gigabit NIC (Edimax PCM-LAN4203, its only ~$20).
So can I expect to get any speed improvement over inbuilt 100Mbits with a gigabit NIC running off cardbus? Can cardbus support these kinds of speeds in the real world? Will the D-Link become a bottleneck?
I realise that for all sorts of reasons I wont get anywhere near gigabit speed when transfering a file in the real world, but since the NIC is only $20, i think it will be worthwhile for me even if it only increases transfer speeds by 5mbps.
