External enclosures.

[rod]

After fitting one desktop XP with an internal DVD R-W,
I am considering avoiding the hassle on the second by
employing and external DVD R-W using an enclosure.

Are there any issues with read-write speeds via USB?
Thanks.

Hi Rod,
I have been an external DVD Rewriter of LG for some time now (via USB) and I
have had no problems whatsoever. I don't care much about the time it takes to
complete a task but I could help you with more information if you can tell me
the approximate figures you are looking at for, say, a 4.7GB DVD-R disc

Not with CD and DVD drives, no.

I use a 16x DVD+/-R drive via USB and it works at 16x without any trouble at
all.

Thanks Guys
puts the mind at ease.
I had read somewhere to burn a full disc
was around 10 minutes, and I have no idea what size
I was thinking a normal 650Mb disc.
I have yet to burn a large disc.
I am in new territory.

Wow! this I like.
My past is linked to images of my clunky Win98
burning at 2x whilst I power nap on the lounge.

Well before you get too excited, you may be disappointed to learn that DVD
burners never burn at 16x for the whole disk. They start at a lower speed
and speed up as the laser moves to the outside of the disc. If they did
burn at 16x on the inside track of the disc, the DVD would be spinning so
fast it would self destruct with the cetrifugal force.

Hey! anything burning faster than 2x is a worthy source of excitement

I have seen CD discs self destruct with centrifugal force,
I think it was the Adam and Jamie on the "Mythbusters"

Only previously damaged discs broke at the speeds generated by the
fastest available drives. They had to resort to extreme measures to
cause undamaged ones to "self-destruct". So just another urban myth.

In that case you may care to work out the RPM required to burn at 16x on a
DVD on the inner tracks. Then if you feel up the task, work out the forces
throughout the disc. A disc in perfect condition will survive, but if it
contains even minor flaws, then destruction of the disc (and maybe even the
drive) is inevitable.
