Flexible storage scalability for Turbo NAS. Simple flexible.
The QNAP REXP-1000 Pro expansion enclosure is designed for expanding the storage space on the Turbo NAS and can support maximum 250TB raw capacity by connecting multiple expansion enclosures via high-speed mini SAS cables. This is especially useful for large data applications, such as video surveillance, data archiving, and TV broadcast storage.

Plug and use, seamless capacity expansion
Simply connect a REXP-1000 Pro to a Turbo NAS and power it on. The Turbo NAS will detect the hard drives in the REXP-1000 Pro as newly installed local drives. The Turbo NAS capacity can be expanded seamlessly by using the powerful QTS Storage Manager.

Missing mode protection
When disconnection of the expansion enclosures occurs, the Turbo NAS enters missing mode automatically 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 when the disconnection is resolved.
