The Maximum Speed Supported field indicates the actual maximum data rate that the

drive supports. This value is returned as the number of kilobytes per/second

(Speed/1000) that the data is read from the drive.

Note that these are the raw data rates and do not reflect any overhead resulting from

headers, error correction data, etc. It is also important to understand that the reported

data rate is a theoretical maximum and the actual data rates to the host will be lower.

The Number of Volume Levels Supported field returns the number of discrete levels. If

the drive only supports turning audio on and off, the Number of Volume Levels field

shall be set to 2.
