Gotta get rid of this stuff!

USB 2.0 is supposed to be around the same speed as Firewire. Every new
motherboard seems to have it. Why woulnd't camcorders use it if its so
common? What are the advantages of Firewire?

I am not sure but I think firewire will transfer Video and Audio at
the same time and rate.

I think it is as simples as Firewire was developed and marketed long before
the protocols for USB 2 were finalised. USB 1.1 was far too slow to be
considered as a viable standard.

Don't know what camera's you've looked at but a quick glance at the Canon
and Panasonic website showed quite a few models that do both firewire and
usb.

One advantage of Firewire is that two firewire devices can be connected
together and communicate with each other without benefit of a computer.

A big disadvantage is that Firewire isn't well supported by Windows
Operating Systems.

A whole lotta camcorders support USB 2.0, limit your selection to one of
those.

When a camera has both firewire and usb interfaces, I'll always use
firewire. I haven't had any trouble using firewire cameras with windows.

The reason Firewire took off around 1998 was DV cameras. At that time USB was
only 12Mb/s, half of DV's 25Mb/s. Why change when firewire works so well?

Which is faster? I heard that USB 2.0 was faster in theory but in real
world situations Firewire is superior.

Again another ass who is positive that he knows and no one else does.
The only solution and reply he has is to reply like a 10 year old
instead of offering a reason for his objection to a reply that stated
that I was not sure. However, one thing I am sure of is that you are
and ass.

I understand that USB can slow down if other USB devices place a demand on
the USB buss - whereas Firewire doesn't have that issue

I think you will find though that they use USB for xferring stills from the
memory card, and firewire for xferring the movies that are on tape. That
definately applies to the i730/750 series anyway

With XP my Firewire card works like a charm - no need for drivers etc, just
works the way it should. No idea about other versions of windows tho

The poster was obviously an Apple user. They tend to blast anything
non-Apple no matter how good it is.

Not exactly true. USB2 is physically faster than firewire. What makes
firewire more appealing is when you have multiple firewire devices. When
chaining of firewire they cross communicate without sending through the
processor first, which translates to real-world speed advantage to firewire.
If you only have 1 firewire device [much like SCSI] USB2 can hold its own.

I've never seen any real-world measurements to back this up. All the
figures indicate the opposite.

And connections are peer-to-peer, no master/slave business. USB has
different connectors for the two ends, but for FireWire the connectors
are the same.

Absolutely NOT an Apple user, a dyed in the wool Windows user. It's just
that I've encountered sooo many problems trying to use external Firewire
hard drives. They simply don't work well for MANY people and the problem is
in Windows, not with Firewire. The problem has been known for a long time
and is well documented, but it is STILL in XP SP/2.

I think the Firewire drive problems are more related to the hardware
than the operating system. I have used external firewire cases ME-320
that sell for about 35 dollars, more or less, and have both USB and
Firewire outlets and can even be chained I have used ide drives from
6 gigs up to 250 gigs and even DVD burners from a half dozen venders
and have yet to run accross a problem in any versions of Win2K or XP.
Probably the best thing to do is to stay away from non standard cases
and drives. Thankfully. they are far and few between unless they are
older hardware. Problems can be found with a lot of hardware if you
look far enough.

UH? I've NEVER had any problems with my external FireWire HD, which is now 3
yrs old. First it got connected to a Win2K PC, then to an XP (no SP) PC & XP
laptop, it also works like a charm with my new XP SP2 PC. Just plug it in...
Only 'problem' I could see is trying to connect it to 2 computers @ the same
time, that never worked, always had to disconnect it from the first one to
get the second one to see it.

There are so many of these devices around, there may be some cheapo models
with problems...

There is no Windows 1394 bug, as others have pointed out.

That documents broken 1394-ATA bridges that crash on writes over 128KB. There
is registry parameter, MaxTransferSize for the sbp2port driver, but no
documentation.
