Too often we search for answers where it is easiest to look, not actually where they can be found. This observational bias is known as the streetlight effect. A common example of this bias happens when internal storage devices are evaluated using simple operating system file copy commands instead of industry standard tools.

This paper discusses I/O bandwidth performance results when using operating system file copy methods versus industry standard tools. The goal is to highlight the need for trusted tools when evaluating the maximum performance capabilities of internal storage devices.
