Overview   This system has 2 independent audio storage systems:

A. Instant Access Buffer
B. Archive Media

These two systems need to be configured for the required retention time.  For example: a 30 channel, 2:1 compression, continuous recording, for 45 days produces 467 GB of data.  The Instant access buffer & the ARCHIVE HDD should be > 467 Gbyte to hold 45 days at the continuous recording.  Because VOX is used, the needed capacity is much smaller.  Both systems can be set not to hold more than for example 45 days of recording.

Using a DVD RAM as archive:  If DVD RAM is used, the storage per site is 4.7 GB, which will not hold a 24-hour period.  DVD RAM disks, depending on recording activity, have to be changed quite frequently.  The instant access system still can be configured to hold 45 days and will always transfer to DVD RAM from the time the RAM disk is reported full.  Nothing will be lost during the DVD RAM changing operations.  Best results (system reliability) are achieved by using only hard disk drives.  Recordings of interest can be removed during recording and played in other compatible systems.
