Hard Drive Performance Dual Processors and Dedicated Audio Drive

[j_jayzatuc]

Hey Everyone,
I'm extremely new to the Macintosh platform and am questioning the performance my new computer will have with Pro Tools LE. I am planning on purchasing Digi 001 but am wondering if I should have purchased a computer with a faster rpm speed and scsi connection...anyway here's what I have-
Power Mac G4 Dual 500 Mhz Processor
40 GB Ultra ATA drive
384 Mb Ram
DVD Ram
Anyway I am trying to understand what a dedicated audio hard drive actually entails. Will it be possible to use the hard drive on my computer now as a dedicated audio drive or will it be rather lacking in performance? Also could I use DVD-Ram as a dedicated audio storage media? Just trying to find out if it will be necessary to have multiple drives and should apply SCSI data transfer. Everyone in this forum seems to be extremely helpful and generous so any correspondence would be greatly appreciated.
Digi 001 KICKS
Thanks
