    External CDRW Speed Advice Needed

    I'm thinking about purchasing an external CDRW to back up departmental files on 5 PIII 500mhz machines with external USB ports. I have been warned that burning on a USB can take a long time, 75 minutes for a full CD. I have no idea what the "normal" (presumably internal ATAPI?) time is. Would Firewire or SCSI be a better external option, and if so I assume I'll need appropriate controller cards? Since the machines all print to LAN, the parallel ports are open. Suggestions welcome.

    We use a HP CD-RW at work, and for a full backup, it only takes about 30 minutes to copy files and create a full CD-R. This is without doing the "test and copy" method... just the copy.

    We normally run these late Friday afternoon, since the majority of our users usually takeoff after lunch.

    The burner writes at 8X speed to a CD-R, 4X to a CD-RW.

    Thanks, Chris. Are you running an internal ATAPI interface?

    Are you asking because the length of time the backup process takes may cause a problem?
    How about backing up to a HD, then simply copying the backup file to the CD burner? You could then afford to write to the CD using the slowest/safest option.

    The files are historical on server. If slow = safe, then perhaps I can tolerate sloth, but I also don't want to slow production down or keep people around after work while the burner runs.

    And the rest of the story is: I'm also interested in the internal/external speed difference because I may get a personal burner for home in a few months.
