1.2.7 Expandable IDE Hard Disk Architecture
All the other HDD-based digital video recorders support only 1-4 hard
disks. If those recorders do support more hard disks, they usually
use RAID (Redundant Arrays of Independent Disks) or SCSI disks,
which are very expensive. With the Expandable IDE Hard Disk
Architecture, the EDR1600 can support up to 18 pieces of IDE hard
disks that are hot swappable. With 40 GB of storage per hard disk,
the system storage is more than 700 GB and virtually unlimited – no
more redundant backup required.
1.2.8 Non-editable Recorded Images
The retrieved images are saved as .MPG files or .MOV files, which can
be played by Media Player or QuickTime. Therefore, those files are
editable by the video editing packages, just like the recorded images
in the other digital video recorders. However, the recorded images
in the hard disks are not editable by the video editing packages.
(They even cannot be seen by those packages.) That is to say, the
recorded images are guaranteed to be the original images.
