Versatile and Robust.
Modular memory card backup system for 4K & UHD.

NSB-25 is modular, meaning the memory card adapter and internal drives can be easily swapped out and replaced. Maybe you change your camera in the future and discover your card reader or backup storage becomes useless for that new camera. But don’t worry with NSB-25. Just change the memory module according to the memory card used by the new camera. There are nine types of memory modules that support almost all types of memory cards used in broadcast cameras. An interchangeable internal drive allows unlimited capacity and safety.

Versatility in memory cards surpported

The memory slot of the NSB-25 can be exchanged according to the memory card in use. That means, the NSB-25 is already compatible with the memory cards you will use for your current and future cameras.

Born for data safety (Multi-copy)

The NSB-25 copies data to the interchangeable drive caddy ‘Bridge Pellet’. The NSB-25 has two slots for ‘Bridge Pellet’. So you can easily copy memory cards into two ‘Bridge Pellets’ simultaneously for redundancy. If you need three copies, connect the USB drive to the USB host port of NSB-25. The NSB-25 will then make copy to two ‘Bridge Pellet’ and one USB drive at the same time, making a total of three copies.

Offloading data at editing system

The interchangeable ‘Bridge Pellet’ itself is a USB3.0 external drive. You can connect it directly to your computer using a USB3.0 cable and edit direct or copy the contents directly by drag-and-drop. NSB-25 has special read only computer I/F port on the main body. You cannot write or modified the contents of ‘Bridge Pellet’ when connected through this ‘computer I/F’ port of NSB-25.
