The AJA PAK Media Module from NEXTO DI is a card module that lets you use AJA PAK cards in the NSB-25, which is a modular memory card backup system for 4K and UHD. The AJA PAK Media Module can be added to one of the two Bridge Pellet slots on your NSB-25 when it is powered off. Next, insert the AJA PAK card into the module after the NSB-25 is powered on. If you have an SSD installed in your NSB-25, data transfers will run at up to 146 MB/s, or 95 MB/s with a hard drive.
