Abstract
A system and method for providing consistent performance in a storage device, such as a solid state drive. A threshold value for command execution time for a command in a category of command (e.g., a read command or a write command) and a command size, is stored in the storage device. When a host command in the category (e.g., a read command) and corresponding size is received, the storage device executes the command, and if it completes execution of the command in a time that is less than the threshold value, the solid state drive waits until an amount of time equal to the threshold value has elapsed before sending the command completion.
