    Hey everybody. I got myself a 20" 2GHz CoreDuo iMac with 2GB of RAM. When importing CDs (into 160kbps AAC) they only import at about 8x. This seems a little slow to me, seeing as my old iMac G4 would get about 12x. Anyone got a similar setup so I can compare speeds? Many thanks.

    I'm gonna assume both cases were 160kbps?

    same speed CD drive?

    Is "error correction " turned off on the CoreDuo? (iTunes>Preferences>Advanced>Importing uncheck "Use error correction when reading Audio CDs"

    Just some slighly random thought thrown out there at 3am....;)

    Well I just imported a CD on my CoreDuo iMac with 512MB Ram to check, it started ripping at ~6X, but got faster as it got to the higher tracks, and it peaked at ~12X for the last 5 tracks or so. I don't remember why higher tracks rip faster but I remember that was the case on my old PC too.

    Was your iMac G4 slot-loading or tray-loading?

    Probably...that's my point. I think tray loading drives tend to have better dynamic balance and can spin discs faster... I think that's the limiting factor that causes rip speeds to be on the low side on recent Macs....

    Yeah because the further from the middle the faster the velocity of the drive, the speed of the drive is measured in rotations/second, so the as the radius further out is larger more data can be read in per rotation.
