Apple's developer documentation states:
"The Ultra DMA IDE interface, also called Ultra-DMA/33 and ATA-5, is an improved version of the EIDE interface."
and later:
"The drive uses the Ultra DMA IDE (integrated drive electronics) interface and is ATA-5 compatible. Current Data Transfer Mode for the drive is UDMA-33."
First, I though ATA-5 was 100MB/s? Second, does this mean I can't get faster than a 33MB/s transfer, even with a different HD? IBM's tech data on the 40GN states it can handle 100MB/s, so it must be the ibook's bus thats the weak link, right? Does the ATA-5 spec provide additional features beyond added speed?
