Hi!

Advantages of firewire approach:
1. Bus design. Internally, the firewire chip doesnt have to ask the CPU to
copy data
to its port, it just does it, while USB devices use the CPU for this task.
2. On cheap laptops (and unfortunat others) the IRQ's between USB &
something else
collide. This means worse performance. (I'm aware that Firewire IRQ's can
collide too,
but I've never seen that phenomena before.)
3. Firewire daisy chaining does still exist, at least for the Echo Audiofire
devices that I have.
4. I run a laptop (so PCI / PCI-E and a lot of other options are out. )
5. From my experiences, Firewire devices seem to be more geared towards
professional use,
while USB targets the "pro-sumer" market. (No flame bait intended here..)

I like the Pure::Dyne, its always done well on my laptop. I've Dyne::Bolic
before Pure::Dyne was
released, and I've been keeping a close eye on AV Linux too.. Between them
I've kept my production
system installed (Pure Dyne), and a range of "testing" partitions with
alternatives for Video / Blender work.

Installing Pure::Dyne is no problem, there's an GUI installer on the Desktop
IIRC.
I'd run it live first, just to check it out to be honest. Not sure about
RAID, never needed it.

Your question 2 has me confuzed I'm afraid, you're asking how its updated?
The same
as any other system... a packet manager. Or do you mean how does the LiveCD
get updated?
I think new ISO's are generated every once in a while... not sure. Check
out RemasterSys if your
hoping to update your Live system and keep it on a CD. (AV Linux is a debian
based RemasterSys distro).

I'm not sure if Pure comes with development tools... It does come with PD,
Processing, Arduino software
etc, but I dont think it has g++, gdb, svn or those installed. That said,
its all a "sudo apt-get install " away.

If you decide to try it, hope it goes well. Your mileage may vary ;-)
Cheers, -Harry

It has been extremely well-behaved.

In your opinion, what is the advantage of the Firewire approach?
Cabling? =A0Replaceability? =A0Ease of multitrack functionality? =A0The
Firewire daisychain capability (does it still exist)?

I just checked out the Pure::Dyne web site. =A0Very promising and
up-to-date, not like I last saw it a while back. =A0Questions:

1. =A0Does it install onto hard drive reasonably easily? =A0I noticed that<=

that page in the wiki isn't there yet, just a title/placeholder. =A0Can=

do RAID-1 without terrible pain?

2. =A0If it's designed explicitly for DVD/USB use (and it looks like it=

is), is that how it's updated? =A0In other words, can I expect to just<=

update my system device and it will use an existing older-version
profile reliably? =A0This would be a very good way to keep a production
machine.

3. =A0Does it include thorough current compilation capabilities?

J.E.B.
