Now that's just curious (and wrong). The laptop has a 16.6MB/s bus on it, yet the drive they put in runs faster that than. ATA/33 and the internal transfer rate of the drive is up to 20MB/s. Why would Apple put a bus in a system that is slower than the drive, when the ATA/33 Specs were out, and so was the G3 Blue and white which had it. Why wouldn't they migrate it over (remember, the B&W came out in 1998, and the Lombard came out in 1999). So why would apple wait so long (2000) before putting ATA/xx on the system.

what's even more tragic, is if I had gotten the Pismo, Apple made the jump from ATA-2 up to ATA-5, which is 66MB/s. That's like a 6x increase. Doesn't make sense... If I had gotten the Pismo, I could have rocked out with that SSD I am going to put in the system a bit better.

Also, is it right to get consistantly only 10MB/s on a 16.6MB/s bus? usually from overhead there is a loss, but I didn't think it would be THAT much of a loss.

It might be my drive though. I am going to throw the old 6GB back in, and see what I get (I will do a test) and it will be interesting if the ATA-5 of the drive is causing that.
