Although it won't be the final answer until someone tells you which
drive is in the FS4, you'll find data here
http://www.storagereview.com/articles/200511/notebook_3.html
that will provide some optimistic numbers at least.
The fastest available drive was a Hitachi Travelstar 7k100 "100GB"
(=80GB) with a sustained read rate of 53 MB/sec at the outer cylinder,
declining to 30MB/sec at the inside. Those are excellent numbers and
at least the outer cylinder number beats a lot of 3 1/2" drives.
If you had one of those in your FS4, copying to a drive at least as
fast, your transfer would begin at a respectable 3GB/minute, declining
to about half that speed toward the center of the (full) drive.
You'll see that the worst drive of the 7 they tested starts out at
30MB/sec and declines to 18MB/sec. That probably isn't the slowest
drive out there, so I haven't done much to answer your question.
Methinks a phone call to Firestore tech support will quickly give you
the numbers you want.
As to using a laptop(s), I note that firewire extenders are relatively
inexpensive - $20 will double the allowed length to 10m and the vendor
claims you can continue adding extenders to 20m without loss of
performance.
I use a PC-hosted product called Scenalyzer Live. It's hardly an
upscale product - from its name, designed to capture and scene-detect
- but it does a responsible job of capture to DV/AVI and allows
multiple instances of itself to run concurrently, each selecting a
different camera for input. It reports dropped frames and frame
errors. The scene detection can be turned off, and having no interest
in that feature nor wanting to add load to the CPU, I do just that.
I've tried it with only two cameras, using a Dell Inspiron with a
1.4GHz (I think) CPU and 512MB of memory, neither of which probably
have anything to do with the throughput.
