Firewire 800MHz vs 400MHz?

Posted this to MovieMaker group some time ago but no replies as yet, maybe
someone here can answer.

I've been reading a bit about Firewire 800MHz.
Will it make a difference when capturing from MiniDV camera? I can't see
how when it's capturing in real time and I don't have any problems with
dropped frames.
I'm assuming I'll need an 800MHz firewire card and maybe a new cable which
supports 800MHz but must the motherboard also support this standard or just
the card?
Related question. Thinking of buying an external SATA/Firewire/USB2 hard
drive, will it make much difference in rendering speed for video? I also
have the option to add internal SATA drive, would that be better?
Currently using a 160GB/7200RPM/8MB cache on Secondary IDE for working space
and storage.

I know of no current model MiniDV camcorders that use the 800mhz IEEE 1394b
standard, so while you idea will work, it will work at the old speed.

Then you'd be fine as you are.

Just the card

It might if you have top of the range components from front to end. You
already know, of course, that the speed of an operation like this is always
govened by the speed of the slowest components.

I also have the option to add internal SATA drive, would that
be better? Currently using a 160GB/7200RPM/8MB cache on Secondary IDE for
working space and storage.

For sheer performance a good well specified internal SATA drive would
probably be better, but the benefit of external storage is that it is
infinately large; starting to fill one drive pack? Just buy another one (I
have 4 here, though to be fair that's 2 each for a Windows desktop and a Mac
laptop!)

Thanks for the replies, will forget about Firewire 800MHz for now and will
probably go for the external SATA/Firewire HDD.

BTW, there are some external hard drive enclosures that are
built for the higher speeds of 800 MHz Firewire. Wiebe Tech,
I believe, has some of these modules.

Instead of external drives, I use disk caddies for both PATA and SATA
drives. These have enclosures that fit into a 5" drive bay and trays
slide in an out that accept hard drives. This allows me to have many
hard drives (for video editing) and I also have my system disk in a
caddy so when I am video editing, I can have a real clean system on a
separate disk.

www.kingwin.com have a bunch of them. I also have InClose for PATA
drives.

Hope this helps!

No known firewire devices made in the past can accomodate 1394B speed.
Their internal speed cannot accomodate the newer firewire bus speed
capability. The only recent one made is a RAID 0 firewire connection box
that incorporates two hard drives simultaneously.

There are SATA and PATA enclosures that fit into a 5.25" bay. Most for PATA
are not "hot" removables, you have to turn off the PC (not standby or
hibernate XP fans) to swap in another. There are also SATA external
removables if you have the external port for it.

The safest way is to use an internal hard drive, other than the partition
and hard drive that contains XP. Point the rendering software to a
partition on that hard drive for the final production location target.
Firewire has the 400 speed limitation, which is about 50 MB/sec for almost
all firewire external drives due to the firewire bus speed. USB2, in my
opinion, has too much software overhead.
