Our Cellquest Macs are Ethernet connected to the campus network, we have
230 Mb MO Disks for personal data storage (for our > 130 users), and CD-R
Writer for data archives. As soon as the 230 MO Disks are full, we burn
them on CD.
I use a Yamaha CDR 100 (4X burning takes only 12-15 min/CD) and Toast Pro
3.01 on the PowerMac. This software is completely transparent, cheap and
peanuts to use. Haven't fried a single CD-R (and burned more than 100 so
far...).
For file transfer from HP or PC, we use the Ethernet connection, and you
can easily burn PC CD's on the PowerMac. With respect to the ease of use
and installation of Windows CD-R Software etc, I would "strongly" recommend
to connect the CD-R Writer to the Mac. The Mac is much more open towards
WinWorld than the other way around..:)
Of course you may need a 1 Gb HD for temporary data storage, but you can
burn directly from 230 Mb or 1.3 Gb MO disks onto the CD if your Mac is
fast enough (PowerMac's usually are).
We use MO disks as intermediate storage, as it allows people to save their
analysis files together with the data, and they only transfer everything on
the CD once they've pretty much finished it all... if you burn the data
directly on the CD, it's a bit difficult to store the analysis pages
together with the data...
Of course you could use a network and file server for the intermediate
storage as well (depends if your users are network savvy - ours are mostly
not... and you also have to consider access speed over the net, as FACS
files tend to be large...
Voila hope that gives you at least one point of view. Don't hesitate to
ask, if you need more details...
Cheers, Matthias
