Appendix D: Hard Drive Configuration and Maintenance 163
Mono audio tracks recorded with 24-bit resolution at 96 kHz require approximately 16.5 MB of hard
disk space per minute (a little more than twice as much as at 44.1 kHz).
Stereo audio tracks recorded with 24-bit resolution at 96 kHz require about 33 MB per minute.
Table 6 lists the required disk space for certain track numbers and track lengths at 88.1 and 96 kHz,
to help you estimate your hard disk usage.
