Easily add additional drive capacity to a Thunderbolt NAS

Simply connect the TX-500P to a Thunderbolt NAS via Thunderbolt 2 cables and power it on. The Thunderbolt NAS will automatically detect the hard drives in the TX-500P as newly-installed local drives. The Thunderbolt NAS capacity can then be seamlessly expanded as a large volume by using the powerful QTS Storage Manager.

Missing mode protection

If your TX-500P is accidentally disconnected, the Thunderbolt NAS enters missing mode and blocks I/O access to protect the stored data. The system can then recover from the missing mode to the normal state with data staying intact.missing-mode TX-X00P

Powerful QTS Storage Manager

The QTS Storage Manager neatly presents tools and options for managing system storage with a modern & intuitive graphical user interface, which greatly simplifies the process of NAS capacity expansion and TX-500P management. IT administrators can easily monitor the health status of TX-500P and the disks within it. When multiple expansion enclosures are connected, the Locate Disk and Locate Enclosure functions assist you in quick TX-500P

Efficient backup solution for Thunderbolt NAS

In addition to expanding an existing volume, you can use the TX-500P as a flexible external storage to perform speedy and secure backup tasks for the Thunderbolt NAS. The QNAP RTRR (Real-Time Remote Replication) or rsync service lets IT administrators back up Thunderbolt NAS data to the TX-500P on a real time or scheduled basis.backup TX-500P

Smart power design

The TX-500P automatically powers on and off with your Thunderbolt NAS, allowing for total convenience and energy TX-500P

Flexible drive selection

The TX-500P offers high flexibility in hard drive selection. IT administrators can choose low-cost but high-capacity SATA HDDs for large data archiving, or high-speed and high-stability SSDs for I/O intensive operations.flexible-drive TX-X00P

Excellent hardware design

The TX-500P includes a full 250W internal PSU to provide ample power even under sustained full load. The well-ventilated chassis and smart fan helps to provide efficient cooling for better stability and reliability, with the fan enabling efficient heat removal even when all 5 drives are under full operation simultaneously.UX fan
