Which of these interfaces is the fastest?

Among these interface types, which one provides the fastest throughput?

A) SATA revision 1.0

B) USB 2.0

C) Firewire 400

D) Fast Ethernet

E) Kevin Harvick’s number 29

The answer: A) SATA revision 1.0

Although SATA revision 1.0 is the relatively old first-generation of SATA technology, the 1.5 gigabits per second of throughput exceed the other technologies listed here:

SATA revision 1.0 = 1.5 gigabits per second
USB 2.0 = 480 megabits per second
Firewire 400 = 400 megabits per second
Fast Ethernet = 100 megabits per second (200 megabits per second using full-duplex)
