Flexibly expand your Thunderbolt NAS storage. Fast and easy.
When expanding data storage capacity, deploying multiple servers can lead to complexity in management and dramatically increased costs. QNAP TX-500P expansion enclosure provides a flexible expansion alternative designed with easy setup in mind for scaling up Thunderbolt NAS storage space via high-speed Thunderbolt 2 (20Gbps) cables. The TX-500P provides an additional 5 hard drives providing up to 40 TB expanded capacity for the Thunderbolt NAS, making it ideal for data backup, 4K digital media collection and video surveillance storage with blazing-fast data transmission performance.

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.
