It is sometimes said that tape is a sequential$-$access medium, whereas a hard disk is a random$-$access medium. In fact, the suitability of a storage device for random access depends on the transfer size. The term streaming transfer rate denotes the rate for a data transfer that is underway, excluding the effect of access latency. In contrast, the effective transfer rate is the ratio of total bytes to total seconds, including overhead time such as access latency.

Suppose we have a computer with the hard disk has an access latency of $19$ milliseconds and a streaming transfer rate of $5$ megabytes per second.

The utilization of a device is the ratio of effective transfer rate to streaming transfer rate. Calculate the utilization of the disk drive for a transfer size of $222$ bytes in percent to $1$ decimal place.
