Quick question, say I have a mobo that has dual lan or I add another network card to a mobo with one. I hook both up to the same LAN would I have increased bandwidth that could be used for say filesharing? would there be any benifits to doing that? Is the software needed to take advantage of that?
 
i have dual lan on my motherboard and i didnt have to increase anything. it worked the same. connected the same and ran the same BUT take 2 lines running from your motherboard to the router/hub/switch and plug them in and if you usually connect at 100 you will now connect at 200... well atleast thats what i have heard.

This is incorrect, plugging in two nics to the same network will not double your speed, or even increase it at all. If you look at your network useage it will typically be around 10mbps under extreme usage (ie massive file transfer) the only reason you would want to use two nics on a personal PC that I can think of is to connect to two different networks simultaneously.

Moral of the story: one nic is all you need! :D

That is also party incorrect. Adding more than one nic WILL increase your bandwidth and shorthen lenghts of transfers... but this is more for massive video/raw transfers and using loadbalancing. Also, to attain this gain from the second nic, they would both have to be very good nics and you would need quite a hefty system on both ends to keep up.

As for home use, rather use gigabit.
 
No matter how fast your network is, your damn hard drive is way slower so it doesn't make a difference.

what about a RAID 5 of 10 - 15 15,000 rpm SCSI drives..
 
you need to have special software for the NICs to be able to "team" them. server NICs come with it usually, but not your $15 realtek jobber or the via onboard thing you're using.

Yep. And those nics costs upwards of $50 each.
 
Having two nics helps most when you wanna have machine bridging two networks, or multiple servers on one physical machine.

That said--fast transfers could be had running gigabit over cat5e or cat6 cables. While I havent seen any gigabit switches out there for the home user, throwing something like the d-link five port gigabit switch under your router will get the job done. Use one of hte ports to uplink to your routher and connect your computers to the other four---via Nics that support 1000 base T connections. Intel sells one such nic for about $25. Any 875P mobo or any nforce2 mobo satisfies these conditions. You'll get crazy fast connections, and without much driver or config hassle at all.

when one full duplex lan cable gives you 100 mbit, what do you get when you connect 2 or more cables to one pc ? Right, 200 mbit or more.

So 4 cables = 400 mbit connection. That is trunking. Only more "expensive" switches support it.
as i said

well atleast thats what i have heard.
