Hardware, Embedded Systems NEC has introduced the world's first USB 3.0 controller. "The muPD720200 device is a host controller for PCs and other digital devices, and is based on the new version of the SuperSpeed USB standard. Supporting the world's fastest USB transfer speeds of up to 5 gigabits per second (Gbps) of data, which is 10 times faster than previous USB 2.0 transfer speeds. The NEC Electronics device, as well as the standard, is fully backward compatible with the USB 2.0, 1.1 and 1.0 versions of the USB standard."

From the sounds of things so far I'm the only one who is going to be sad to see FireWire get pushed out of the way even more than before. I hope it sticks around for the video and hard drive side of things.

There is so much more to FireWire than just the speeds... the smart devices not needing a computer as the middle man. I LOVE the ability to plug a firewire drive right into my HD Cam and have the footage go right to the drive. Can't do that with USB. And the offloading on the processor, I hope with USB 3 they figure out how to make things happen without being so processor dependent!!

I agree with you that FireWire has many positive things in its design, but in point of fact, most entry level implementations of FireWire don't really show these things off. I know by measuring CPU loads for example, that the cheap on-board FireWire port in my old Athlon XP board uses just as much CPU power as the USB ports. Given that I suspect that most people have a FireWire implemnentation rather like mine, for them there really isn't an advantage.

"Intel announces, demonstrates USB 3.0"

With Intel being one of the forces behind the development of USB 3.0 I wouldn't hold out much hope of that. To be honest, with the power of modern CPU's and being multi-core I doubt you would notice a difference. I saw a test one time where someone compared software RAID vs a separate controller board. The CPU was actually faster in most cases. And this was a couple of years ago with a single core CPU.

I love my firewire devices. And yes, the CPU load and data throughput on FW400 is much better that USB2.0 devices. I haven't tried FW800 yet.

As far as I understand the USB3 cables use fire optic and copper. Isn't that going to push the price of USB3 cables up tremendously?

I can't agree more. I just found this bit of information on the net about Firewire S3200. Because the hardware device contains the firewire hardware, the existing FW800 port can be used for S3200 speeds. How cool is that! :-) With such good news, firewire should really push that in their marketing.

http://www.techiesouls.com/2008/12/03/usb-30-vs-firewire-3200/
FireWire 3200 has a maximum capability of a 3.2Gbps transfer rate, which is 1.6Gbps slower than USB 3.0. However, it should also be noted that the P2P (peer to peer) architecture can usually deliver a higher percentage of the maximum rate than the master/slave architecture of USB can. FireWire 3200 is also backwards compatible with FireWire 800, and you can even plug your new FireWire 3200 hardware into the old FireWire 800 ports and instantly get the new 3.2Gbps speed. FireWire still has an edge in power output over USB too, even after all the improvements, making it even more capable of charging items or powering them through the cables.

I'm really surprised that no one has jumped on the bandwagon with marketing along with, "want speed improvements with USB? throw out your old gear!". I know for me if I could upgrade performance without needing to throw away my old devices, it would be a big incentive for me to upgrade to the new version.

Firewire unfortunately is one of those pieces of technology that are superior in every regard but due to sloppy marketing - never really makes it beyond a niche area. I blame marketing because I truly believe that if end users saw those benefits and the savings as a result they would be more than happy to pay the extra $2 or so more for a computer if it saves them $400 on being able to keep their old firewire device and gain the performance benefits.
