ATA/66 uses both rising edge and falling edge but doubles
UDMA/33
transfer rate. The data transfer rate is 4 times of the PIO mode 4 or
DMA mode 2, 16.6MB/s x4 = 66MB/s. To use ATA/66, you need special ATA/66 IDE cable.

ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as
ATA/66
but clock cycle time is
reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the
same as ATA/66.
