Product Specifications

Expand storage capacity by attaching compatible USB (version 2)
hard drives to the USB ports.
The 10/100/1000 Mbps auto-negotiating Ethernet ports allow the
NSA to detect the speed of incoming transmissions and adjust
appropriately without manual intervention. They allow data transfers
of either 100 Mbps or 1000 Mbps in either half-duplex or full-duplex
mode depending on your Ethernet network. Use 8-wire Ethernet
cables for Gigabit connections. The ports are also auto-crossover
(MDI/MDI-X) meaning it automatically adjusts to either a crossover or
straight-through Ethernet cable.
Serial ATA is an interface technology that allows high speed data
transfer. Serial ATA also allows more efficient internal airflow and
also smaller chassis design.
You can remove and install hard drives while the NSA is operating.
Audible alarm buzzer triggered by logs of a user-specified severity
level.
Use the reset button to reset the NSA (user name to "admin", default
password to "1234", default IP address to 192.168.1.3 with subnet
mask of 255.255.255.0) or restore the factory default configuration
file (all configurations, including shares, users, passwords and so on
are returned to the original configurations).
RAID 0 with 2,3, or 4 hard drives.
RAID 1 with 2 hard drives
RAID 5 with 3 or 4 hard drives
RAID 10 (1+0) with 4 hard drives
JBOD with 1,2,3, or 4 hard drives
Create separate archive backups or synchronize a copy.
A snapshot is a backup of your NSA data on the NSA. If files within a
volume become infected or corrupted, you can revert the volume back
to a previous snapshot. It's a good idea to create a snapshot before
backing up data, to be sure you're backing up consistent data even if
the backup is still running several hours later.
