Same RAID functionality aseRAID, yet nRAID allows direct connection to any network without any drivers need to be loaded, fully compatibale with Unix, Linux, MAC OS X and Windows platforms. nRAID is designed from the ground up for easy expansion and secure data storage and sharing of all your files in a fast, easy, cost-effective and extremly high fault tolerance system thru Web-base management.

Network Protocols
- File Sharing: FTP, SMB over TCP/IP, NBNS
- Web - Browsers: HTTP1.0 and HTML2.0 for for Web-based system management
- DHCP Server/Client auto detect/ Static IP), SNTP Client

Central Digital Database
nRAID may easily adapt as the central storage unit for all business or entertainment needs.

High Reliable Storage
The nRAID System provides RAID levels 0, 1, 0+1, 3 and 5 or JBOD configurations to provided the high reliable data sotrage space, our nRAID system utilizes high-performance 64bit RISC processor, 64bit memory architecure, built-in 64MB SDRAM cache buffer and 66MHz/32bit path at burst rate upto 266MB/sec to control five (5) hot-swapt ATA-133 HDD (no size limited) with unprecedented performance whether Share or Independent Volume thru 10/100mbps (RJ-45) connection or USB2.0
