for the location of the LEDs.

Hardware-RAID NAS System Drive Configuration
The NAS system with hardware RAID contains four IDE hard drives that are in a RAID configuration. Unlike the software-RAID NAS system where Windows
Powered controls the hard drives, the drives in the hardware-RAID NAS system are controlled by a RAID controller card installed in a PCI expansion slot. All
four IDE hard drives appear as only two volumes to the operating system. See
. The operating system and boot sectors are installed
on one RAID 5 volume that is spanned across the four IDE hard drives. Data can be stored on the other RAID 5 volume that is also spanned across the four
IDE hard drives.

NOTICE:
The software RAID and hardware RAID hard-drive carriers operate differently and are not interchangeable between the two types of NAS
systems. The hardware RAID hard-drive carriers have a "HW-RAID" identification label and the software RAID hard-drive carriers have a "SW-RAID"
identification label.
NOTE:
RAID 1 hard-drive configurations are not supported on hardware-RAID NAS systems.
