Fit more storage into a shallow rack

At 292.1mm deep, this short-depth NAS suits compact racks and media cabinets. Its 1U chassis helps make efficient use of rack space while leaving room for cabling and ventilation.

Four hot-swap drive bays simplify maintenance. The NAS supports online RAID expansion and migration, plus RAID rebuild and automatic rebuild functions.

Move files quickly across your network

Two 10GbE SFP+ ports and two 2.5GbE Ethernet ports support high-bandwidth file sharing and backup workflows. Link aggregation and load balancing help you make better use of compatible network connections.

The four-core 2.2GHz processor and 4GB of DDR4 memory provide the platform for everyday NAS tasks. You can upgrade the memory to a maximum of 32GB.
