To facilitate file sharing between different users or platforms, the ZyXEL NSA-2401 network storage 

appliance meets the need of small business users with outstanding performance and massive 

capacity designed for mission-critical storage management. Its 800 MHz-grade CPU, 256 MB DDR II 

memory and dual Gigabit LAN ports empower data reading/writing and network transmission 

performance outperforming the competition with the best price/performance ratio.

In addition to typical RAID functionalities, the NSA-2401 provides a “hot spare” feature (RAID1 + Spare, 

RAID5 + Spare) to reduce down time in the event of driver failure. If any HDD failure occurs, the spare 

HDD in the NSA-2401 will automatically take over from the failed one and continue to function 

without corrupting the files, or interrupting regular NAS operations.

The NSA-2401 can also collaborate with an optional UPS device to protect files and databases from 

sudden power failures or surges. With the NSA-2401 monitoring the power level from the UPS (via 

USB) port, the IT staff can be informed of power failure or low UPS power level via e-mail in order to 

backup/save important data or shutdown the system safely in time. All these features ensure 

maximum device availability.
