Key specifications at a glance

Fit more storage into a compact rack

At 292.1mm deep, this NAS can suit shorter racks and compact media cabinets. The rack-mount kit is included, making it easier to integrate into a suitable rack.

Four hot-swap drive bays simplify drive replacement and maintenance. Choose from RAID 0, 1, 5, 6, 10 or JBOD, with online RAID migration and expansion supported. RAID choice affects usable capacity and protection, so plan your storage configuration around your needs.

Connect teams at higher speeds

Two 10GbE SFP+ ports and two 2.5GbE RJ45 ports provide options for high-speed network connections. Link aggregation and load balancing can help manage network traffic across supported connections.

For workloads that need faster storage response, two built-in M.2 2280 slots support NVMe SSD caching. The SSDs are sold separately. Memory can also be upgraded from 4GB to a maximum of 32GB to support heavier multitasking.

Back up and manage business data

QNAP QTS supports file sharing, snapshots and backup to cloud storage or iSCSI LUNs. Snapshot support lets you record data at a point in time and restore it when needed.

The NAS supports Windows, Mac and Linux systems. S.M.A.R.T. monitoring and bad-block scanning help you check drive health and identify issues.
