Benefit of Using SATA Technology
High Performance
Using single device connection which eliminate the master/slave issues and allow faster transfer rate without latency and delay.
High Data Integrity
Offers error checking and error correcting capabilities. The end-to-end integrity of transferred commands and data can be guaranteed across the serial bus.
High System Reliability
Thinner and smaller cables and Low Voltage Differential (LVD) power signaling allow more efficient airflow and generates less heat in the system.
High Usability
Easy installation with jumperless design.

Powerful function
Snapshots are fast point-in-time copies of volumes. Taking snapshots can be backed up in less than one second. Not impacting server performance and productive activities, it is the ultimate solution to satisfying short-term backup needs.
Data Archiving
Data Archiving can help moving out historical data regularly. It allows storage administrators to filter out files by their ages, last modified time or archive bits, and then move them to a less expensive optical media.
Optional feature

Key Benefits
Optimized for high performance
NAStorage™ ۴۴۲۰R provides the unprecedented throughput for file-serving, making it more cost effective than general purpose servers.
The main goal of SmartExtend is to manage storage resource for multiple NAStorage units in the network as a single IP Storage network. That’s mean better resource utilization, ease of storage management and simpler expansion of storage infrastructure.
Enable fast data replication and NAS-to-NAS backup by employing differential block transfer to speed up the process. All the backups are kept online for easy data restoration.
Enterprise-class antivirus protection
High-performance real-time virus scanning protection with automatic virus pattern updates from Trend Micro ensuring data integrity for the NAStorage™ ۴۴۲۰R.
NAStorage™ ۴۴۲۰R supports snapshot function which creates a read-only copy (in a flash of a second) of the contents of a NAS Server at a particular point in time. User can easily restore previous versions of files or folders without having to contact a system administrator.
NAStorage™ ۴۴۲۰R supports Network Data Management Protocol (NDMP) which is an open standard protocol for enterprise-wide backup of heterogeneous network-attached storage.
