Maximum Theoretical Transfer Rate



The Maximum Theoretical Transfer Rate (or Optimal Throughput) are numerical values used to denote the maximum data transfer rates of which a device is capable under ideal operating conditions. During typical use, the actual transfer rate will be much less than in theory.

Example: USB 2.0 is capable of data transfers of up to 480Mbps. However, the actual throughput would be much less than 480Mbps, based on a number of factors including host processor speed, host adapter performance, bus configuration, host software, disk drive characteristics and performance.
