ATA/66, data transfer rate is 16.6MHz x 4 = 66MB/s.
ATA/100, data transfer rate is 16.6MHz x 6 = 100MB/s.
ATA/133, data transfer rate is 16.6MHz x 8 = 133MB/s.
(ATA/133 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 30ns.)

Bluetooth is a wireless transferring technology that enables short-range wireless connections between desktop and laptop computers,
personal digital assistants (PDAs), cellular phones, printers, scanners, digital cameras and even home appliances. The principle of
Bluetooth (a chipset) is to transfer information and voices at the frequency of ISM Band. Every Bluetooth technology devices do come
with a standard address for you to connect one-to-one or one-to-seven (to form a Pico-net), with transferring range up to 10 meters (100
meters to follow), using low power radio. Bluetooth do not only possess high transfer rate of 1MB/s, it also could be encrypted with pin
code. With hopping rate of 1600 hops per second, it's difficult to be intercepted and are less interrupted by electromagnetic wave.
