I got the second Optical drive installed into my MacPro a couple weeks ago & I was wondering what the difference is between the DVD-RW, that came with the machine & the DVD-RAM that I Installed? Both seem to work the same as far as I can tell. BTW, I have Toast 9 on the way as soon as its available, I pre-ordered from macmall with a rebate. Waiting on deliveries this week is going to make time drag. I have Toast, an ACD 30" & A Seagate 1tb HD on the way currently. Anyway, what's the scoop with DVD-RW vs DVD_Ram?
