USB100KiB

USB100KiB refers to a theoretical or hypothetical USB data transfer rate. The designation suggests a maximum throughput of 100 kibibytes per second. A kibibyte (KiB) is a unit of digital information equal to 1024 bytes. Therefore, 100 KiB is equivalent to 102400 bytes. This rate is significantly slower than common USB standards like USB 2.0, which can achieve theoretical speeds of up to 480 megabits per second (Mbps), or approximately 60 megabytes per second (MBps).

The USB100KiB designation might be encountered in specific, niche contexts, such as in embedded systems, older hardware limitations, or in discussions about very low-bandwidth USB applications. It is not a recognized official USB standard. For practical purposes, modern USB interfaces operate at much higher speeds, making a 100 KiB/s transfer rate exceptionally slow. Understanding this rate requires differentiating it from megabytes or megabits per second, which are the more common units for measuring USB performance. The distinction between kibibytes and kilobytes (1000 bytes) is also important for precise calculation, though in casual discussion, the difference might be overlooked.
