[QUOTE="josch.hh, post: 292990, member: 71222"] Thanks for your reply. I would really like to know something about the power consumption. Can someone test this maybe? I am sure other people would like to know too. :) As everyone knows - IT is getting "green". I just read the link and it is the perfect answer. I would say that this small piece of text is so interesting, that i would like to put it here in the thread (Just in case the remote side will not be available some day). Here it is: ===================================================== [SIZE="3"][B]FireWire vs. USB 2.0[/B] [I]FireWire - Still the Performance King![/I][/SIZE] Need to connect a FireWire device or a USB device and you don't have the appropriate interface on your computer?

But, differences in the architecture of the two interfaces have a huge impact on the actual sustained "real world" throughput. And for those seeking high-performance, sustained throughput is what it's all about (reading and writing files to an external hard drive for example). [B]Architecture - FireWire vs. USB 2.0[/B] FireWire, built from the ground up for speed, uses a "Peer-to-Peer" architecture in which the peripherals are intelligent and can negotiate bus conflicts to determine which device can best control a data transfer USB 2.0 uses a "Master-Slave" architecture in which the computer handles all arbitration functions and dictates data flow to, from and between the attached peripherals (adding additional system overhead and resulting in slower, less-efficient data flow control) [B]Performance Comparison - FireWire vs. USB 2.0[/B] Read and write tests to the same IDE hard drive connected using FireWire and then USB 2.0 show: [B][I]Read Test:[/I][/B] 5000 files (300 MB total) FireWire was 33% faster than USB 2.0 160 files (650MB total) FireWire was 70% faster than USB 2.0 [B][I]Write Test:[/I][/B] 5000 files (300 MB total) FireWire was 16% faster than USB 2.0 160 files (650MB total) FireWire was 48% faster than USB 2.0 [B]FireWire - Still the Performance King![/B] As the performance comparison shown above confirms, FireWire remains the performance leader.
