Bytes Per Second (Bps)
Bytes per second (Bps) is a unit of data transfer rate that measures the amount of digital information transmitted or processed per second, expressed in bytes. A single byte consists of 8 bits per byte, making Bps eight times larger than bps (bits per second). This data rate metric is widely used in storage, networking, and computing to quantify speed of data movement. For example, file download speeds on modern internet connections are often measured in megabytes per second (MBps), providing an easily understandable value for users compared to bps.

The distinction between Bps and bps is crucial in evaluating system performance. While bps is often used in network data rates, Bps is more common in describing storage transfer rates. For instance, modern NVMe SSDs achieve speeds exceeding 7 GBps (gigabytes per second) when reading data or writing data, which equates to 56 Gbps. This representation aligns better with how users perceive data volumes in practical scenarios, such as transferring files or accessing media.

Bps is scalable and often expressed in terms like kilobytes per second (KBps), megabytes per second (MBps), or gigabytes per second (GBps). Technologies like USB 3.2 and Thunderbolt 4 rely on Bps to highlight their data transfer capabilities. For example, Thunderbolt 4, introduced in 2020, supports data transfer rates up to 5 GBps, enabling rapid data movement for external storage and peripherals. This scalability makes Bps a vital speed metric in assessing the data transfer efficiency and data transfer speed of modern digital systems.
