Both work using the plug-and-play, hot-pluggable technology, meaning you can plug a device into your computer while the computer is on, and the computer will recognized it and start to communicate with it assuming the driver has already been installed.
That means in order to communicate with each other though a USB, two devices also have to be connected to a computer. Meanwhile, a FireWire connection can be completed directly between the two devices without a need for a computer in the middle. That's why USB is used as the standard in most computers' high-speed buses. Still, neither is prohibitively expensive and both allow numerous devices to be connected to computer easily.
Connect and share knowledge within a single location that is structured and easy to search. Which external connection has the highest data throughput with respect to the headers used? I would appreciate a slowest to fastest list including USB 2. However, this does not provide the actual answer. As an example, FireWire is a serial connection. The entire Mbps is available for data transfer.
USB 2. When considering throughput the list looks entirely different. Theoretical maximum and real-world speeds can vary wildly, and only some significant actual testing will give meaningful answers. But even this leaves some question, as perhaps their specific USB 3. Another seems to suggest USB 3. This is a perfect example of an incredibly poorly worded question arriving at the incorrect "popular" answer.
This means that the theoretical maximum throughput data rate is closer to Mbps. That is, control signals are sent through the same pipe that is used to move data. Firewire does not have this restriction to consider. This is not the only example of why answering a question like this by citing theoretical maximums does not provide a correct answer.
Sign up to join this community. Using the same hard drive, but connected to our Mac Pro, we found the FireWire connection to be 19 percent faster than the USB on the copy to the external drive, 21 percent faster on both the duplication test and the copy files test, and exactly the same in terms of performance difference on the AJA read and write tests as with the MacBook Pro.
The My Book tested on the Mac Pro showed the FireWire connection to be 48 percent faster than USB at copying the file to the external drive, 54 percent faster duplicating the file, and 49 percent faster copying over our files and folders.
The AJA write tests showed the connection writing twice as many megabytes per second as the USB connection, and 49 percent faster reading. We also tested a zippy little Verbatim portable drive, which was 23 percent faster than USB in the copy to external test on the MacBook Pro, 21 percent faster at the duplication test, 14 percent faster on the file copy test, 42 percent faster on the AJA write throughput, and 8 percent faster on the AJA read throughput.
Connected via FireWire , we saw FireWire speeds 42 percent faster than USB at our copy to external test, 55 percent faster on our duplication test, 32 percent faster in the files test, and two times faster in the AJA read and write scores.
It was intended to replace the multitude of connectors at the back of PCs, as well as to simplify software configuration of communication devices. The USB 2. The USB 3. Its maximum transfer rate is up to 10 times faster than the USB 2. Although high-speed USB 2. For example, the FireWire host interface supports memory-mapped devices, which allows high-level protocols to run without loading the host CPU with interrupts and buffer-copy operations.
Besides throughput, other differences are that it uses simpler bus networking, provides more power over the chain, more reliable data transfer, and uses fewer CPU resources.
