 on your network. It features up to 10TB** of storage 

capacity in five bays expandable with its two USB and two eSATA

Ethernet connection. Recommended for networks of up to 300 users,

for high capacity and high transfer speed rates.

RAID Protection

Thanks to the secure RAID modes, including RAID 5 and RAID 6, 
the 5big Network 2 enables you to keep data access even if one  
disk fails. The hot-swappable disk trays*** even allow maintenance 
without affecting your workflow. “Spare” modes allow a second 
level of protection; a sort of “automatic maintenance” that will 
immediately start rebuilding the RAID protection in case of a disk  
failure. And with room for five disks, the 5big offers more capacity 
than four-disk solutions in almost every RAID mode. Extra spare 
disks are available as an option for immediate replacement. 

• Fast access to your NAS—performance up to 70MB/s

*

• RAID 5 or RAID 6 (hot-swap) modes in case of disk failure
• Failover and load balancing options using two LAN interfaces
• iSCSI target client
• Dynamic DNS remote access
