Single drive systems
The MaxDisks default value 1, dictates that reads from all
the hard drives are sequential, i.e. only one read of MPEG
data occurs at a time. This is acceptable when using a single
content drive. However reading from multiple content
drives, a read from one drive must complete before a read
on another drive can start. This does not take advantage of
the performance potential of a multi-drive system.
Multi-drive systems
The use of multiple content drives in a system is useful
when it is not possible to store all MPEG content on a single
drive or there are multiple channels playing different
content. Each channel group has its own drive(s) for
content storage.
For simplified mapping, divide the number of channels
evenly and sequentially across multiple drives.
