    I am surprised to find that my PB 12" 1.5GHz could import CD faster than my iMac 24". I think there must be something wrong with my iMac??

    I was using the same CD and same setting: 192kps AAC vbr, error correct.

    My iMac get about 7.x speed but my PB is about 11.x.

    Any ideas?

    My iMac 24" basically import all kinds of CD at 5.x - 7.x speed.

    Gone but not forgotten.
    Do you have some PowerPC applications running on the iMac that require Rosetta to take memory from iTunes or are otherwise inhibiting all-out performance?

    no such problem.

    After a little search at apple.com discussion, I found other people have similar problems too. Some claim it is because the superdrive from MATSHITA (Panasonic) sucks. I doubt it because my PB also uses MATSHITA superdrive.

    I am now really unhappy about my iMac.

    I have the same problem. My emac kicks the crap out of my intel imac when it comes to importing music, but my mac mini is a lot faster then both machines and its a core solo. My tech guy at school says imac are slower at burning and stuff because they do something to slow the hard drive down. He said there is a 3rd party app that fixes it.

    I think the iMac actually slows the optical drive down, watch the introduction of the iMac G4 where steve actually says that they'd have to slow the optical drive down if they made the iMac look like it does today..

    Yes I've noticed my iMac superdrive is way slower than any other cd drive I use because it is vertical. They have to slow down the drive so it works properly when tilted vertically. It takes longer to initially load the files off the CD during Windows installation with boot camp on my iMac 2.0 ghz than on my 700 mhz celeron...

    I see. Then why did they do it!
    I love the G4 iMac better.

    My MacBook (sig) imports music at around 20x (192kbps AAC) in iTunes

    When I use the external firewire CDR drive that I got a few years ago to go with my beige G3, my MBP sometimes hits speeds of 42X! :eek:
    However, with the internal drive, it's MUCH slower.
    I used to have an imac G5 and noticed the same problem. With the external it would max out around 25X but with the internal it was half that or less.
    I've also noticed that speeds vary widely depending on which CD I'm ripping. It must have something to do with the way different suppliers manufacture or encode the discs.
    It seems strange though that your PB drive is faster. I would expect them to be similar. In fact, your PB drive sounds faster than my MBP drive.

    Yes, drives make a huge difference...but It's most likely the velocity engine. Yes the g4 is waayyyy slower than the core duo, but the velocity engine was a really interesting technology and mp3 ripping/encoding was one of it's specialities. SSE3 in intel core 2's is similiar, but 1. not as good 2. isn't well taken advantage of anyway in apple's os or apps

    Yeah I get about the same speed on my Core Duo iMac's internal drive.

    That's depressing. My 2.0 ghz MBP rarely breaks 10x during import (128 AAC).

    I should try an external firewire drive and see if that gives better results.

    Well to see if it is the processor (velocity engine?) or the drive just rip to a raw format like WAV...

    So since the iMac's drive is slow in vertical does the smae apply for current gen consoles which have all taken to being placed vertically?
