I just hope it is not limited to just chips on the motherboards (a la need a new mobo) but also maybe an add in PCIe card.
Well, that's the least of our worries. It's not copper wire based, so everyone with a networked home or business would need to gut it in order to lay fiber down. I'd have no problem with buying a new board if that's all it needed. Fiber is expensive, hard to terminate, need special tools, no sharp bends...man; if typical wiring took me a month to get done, fiber would take me half a year.
Some boards already have the USB 3.0 on the rear I/O (Extreme III
), but the products to plug into them to try it out are slim to none. 170MB/s sounds nice, but I'd still rather lean on a fat network like Intel's working on with a large capacity file storing PC on one end of a cable. One TB just isn't enough for backup these days.
10G/s would be way ahead of what is needed for that though. With SSD's not going past 500MB/s in any configuration, 4TB of spindle drives don't even tap out S/ATA 3G, let alone 6G. Light Peak is progress, but we have a long way to go as home consumers to really need it at this point. Hopefully late next year we'll see it roll out.
