why my DVD-RAM is so slow?

    hi all,

    i use a DVD-RAM to backup audio projects (done on Nuendo).
    it's internal SCSI-2 drive.

    the problem is, copying files from and to it is way too slow.
    example: 700MB project folder ==> it took 25 minutes!
    i mean, it would take half that time to burn it on CD.
    imagine how long for a 2GB, 3GB projects or more.

    the manual for the drive states sustained transfer rates as follows:

    1,385KB/s for 2.6GB discs (that's 81MB/min)
    2,770KB/s for 4.7GB discs (double as above)

    i've been using 2.6GB discs.

    does anybody know why it's so slow?

    here is my setup:
    P3 1GHz, 512MB RAM, 30GB IDE drive, W98SE, Panasonic LF-D201 DVD-RAM drive

    any help would be much appreciated,
    many thanks in advance,

    Fabrice

    Typically DVD RAM's arent that fast on the writing. It's a great way to back up but granted it's notthat fast.
    Things to check are your SCSI card's throuhput to see if you can boost it higher..make sure it's properly terminated..etc ect

    thanx for the reply Opus.

    i would be happy with the figures the manual states. but i'm not even getting half as fast.

    do i have to open the cover to check the card's thruput and termination?

    basicly, i don't know how to do it; i'm useless when it comes to computers; i just rely on other people's help.

    many thanks,
    Fabrice

    To check your SCSI throughput speed you need to go into the SCSI bios when booting up your machine and see what it is set for..
    what SCSI card do you have?
