13 questions
Frequently asked questions about this product
Compiled from manufacturer information
Does this hard drive support connection to general NVRs?

How many 4K cameras can be used simultaneously?
Supports up to 64 simultaneous single-stream cameras, including 4K cameras within the system NVR limits and actual bandwidth usage
How long can 12TB capacity last in a 24/7 CCTV system?
With 550TB/year endurance, the system can record continuously for over 20 years without frequent drive replacement, depending on camera resolution and frame rate
Do I need to install additional software to use WDDA?
No additional software installation is required, but an NVR or video analytics system that supports WDDA is needed to access drive health data and receive early warnings
Can it be used with general CCTV systems, or does it require special models?
It works with standard SATA-based CCTV systems, but to fully utilize AllFrame AI and WDDA features, it is recommended to use with intelligent CCTV systems or enterprise-level NVRs that support these features
What is the maximum read/write data transfer speed?
Maximum data transfer speed reaches 272MB/s, which is sufficient for simultaneous recording of multiple 4K cameras, especially when used with OptiNAND and AllFrame AI technologies
Can it be installed in a rack enclosure?
