It’s been a very long time since 1Gb Ethernet was cheap, and file sizes have kept growing. I really want 10Gb Ethernet for both home and work.
Alas, this is just an ad for Intel, but at least it TALKS about 10Gb as something people would actually have:
Stuff is still expensive
Adapters are $200 to $500, and switches are $1000 to $5000.
There is a motherboard with 10GB on board – http://www.supermicro.com/products/motherboard/QPI/5500/X8DTU_.cfm?TYP=SAS&LAN=10 – about $900.
What you want to buy is 10GBASE-T as it uses Cat6 or Cat6a twisted pair cables.
Netgear has an 8-port 10GBASE-T switche – http://www.netgear.com/landing/10gigabit/ – $850 on Amazon – http://www.amazon.com/Netgear-8-Port-10-Gigabit-ProSafe-Switch/dp/B00B46AEE6.
Intel 10GBASE-T NICs are about $350 for single-port – http://www.amazon.com/Intel-X540T1-10GBase-T-Ethernet-Coverged/dp/B008NJPL7C/ref=pd_sim_pc_3 – and $500 for dual port – http://www.amazon.com/Intel-Ethernet-Converged-Network-X540T2/dp/B0077CS9UM/ref=pd_bxgy_pc_text_y
So a small network with 4 computers on 10Gb would be around $2500 when you add cables, or about $600 a port. For 8 computers, it still works out to about $450 a port.
Unfortunate that bonding isn’t an answer.
