What is the maximum data rate of FireWire 400?

FireWire 400, also known as IEEE 1394a, has a maximum data rate of 400 Megabits per second. This standard was widely used for connecting devices such as external hard drives, cameras, and other peripherals. The designation "FireWire 400" directly refers to this speed, indicating its capability to transfer data at that rate.

While other options present higher data rates, they correspond to different FireWire standards: FireWire 800 offers a maximum data rate of 800 Megabits per second and is indicative of the IEEE 1394b standard. Therefore, the choice reflecting the accurate maximum data rate specific to FireWire 400 is indeed 400 Megabits per second. Understanding these distinctions is essential for correctly identifying the specifications and capabilities of various data interfaces.
