Core specifications at a glance

Fast connections for shared work

Two 10GbE SFP+ ports and two 2.5GbE RJ-45 ports give you options for high-speed network access. Link aggregation and load balancing can help make use of multiple connections. In practice, your network equipment and connected devices must support the speeds you want to use.

Four bays, with room to grow

The four hot-swap bays support HDDs and SSDs, so you can choose capacity or storage type to suit your workload. The NAS is diskless, which lets you select and install drives separately. RAID 0, 1, 5, 6, 10 and JBOD are supported, with online RAID migration and expansion available.

Two built-in M.2 2280 NVMe slots support SSD caching. This can help reduce access latency for frequently used data. M.2 SSDs are sold separately.

QTS tools for backup and protection

QNAP QTS includes file sharing, backup functions and snapshots. Snapshots let you restore data to an earlier point, while cloud and iSCSI LUN backup features support different backup workflows. The NAS also supports S.M.A.R.T. monitoring and bad-block scanning to help you check drive health.

Check your rack and network

• Confirm your rack has space for a 1U chassis measuring 291 mm deep.
• Check that your chosen HDDs or SSDs suit the four drive bays.
• Confirm your network equipment supports the SFP+ or RJ-45 connections and speeds you plan to use.
• Check whether you want to add M.2 2280 NVMe SSDs for caching.
