Discussion Overview
The discussion centers around achieving the maximum data transfer speed of 480 Mbit/s with USB 2.0, exploring the limitations and requirements for reaching this speed in practical applications. Participants examine both theoretical and practical aspects of data transfer, including hardware considerations and operating system capabilities.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- JoAr questions how to achieve the maximum data transfer speed of 480 Mbit/s with USB 2.0, indicating a lack of clear answers.
- One participant suggests that the protocol's capability may exceed the ability of Windows to supply data at that rate, proposing the construction of a custom circuit for testing.
- Another participant clarifies that 480 Mbit/s translates to 60 Mega-Bytes per second, relating it to the data rate of video images.
- A different viewpoint emphasizes that the quoted bandwidth figures depend on packet assembly and transmission frequency, and that practical throughput may be limited by the ability to manage receive/transmit buffers effectively.
- JoAr responds to earlier comments by questioning the operating system's ability to handle data rates, referencing external resources that suggest it can.
- JoAr also corrects a misunderstanding regarding the data rate, reaffirming that it is indeed 480 Mbit/s, not bytes.
Areas of Agreement / Disagreement
Participants express differing views on the capabilities of operating systems and the practical limitations of achieving the maximum USB 2.0 data transfer speed. There is no consensus on the best approach to achieve the desired data rates, and multiple competing perspectives remain.
Contextual Notes
Limitations include assumptions about the operating system's data handling capabilities and the need for custom hardware solutions. The discussion does not resolve the technical challenges related to buffer management and throughput in practical scenarios.
