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.
