two questions: why USB2 instead of USB3 and will there be a multi-nic version at some point?

e14 Contributor

Why is the PI using USB2 instead of USB3 at this point and is there any plan to come out with a multi-nic version of the card?  I can see this being used as a very nice little firewall if one could stack, say, 3 nics on the card.

  • USB2 is built right into the CPU - USB3 would require additional hardware, and the Raspberry Pi probably couldn't move data fast enough to saturate USB2 anyway.  I think I heard it has something like 60MB/s of bandwidth for ALL the IO, including USB.

     

    I doubt there will ever be a multi NIC version, but there really doesn't need to be when USB hubs and ethernet adaptors are avaliable for $3.99.

    I am not sure of the need for a multi nic version. If you want a cheap multi nic system running linux you could just get a cheap router and flash open-wrt on it

    Yeah. But I pay about $60 for a cheap open-wrt-capable router. And only $35 for the RPi. And with  a router you end up with: Is this thing actually the same as the one that Openwrt runs on?

     

    Anyway, for some time to come, RPi will, with an extra USB-ethernet interface be fast enough to saturate the WAN connection  for most people.
