12 TB surveillance drive
The Western Digital WD121PURZ is a 12 TB 3.5 inch internal hard drive built for 24/7 surveillance recording. It uses SATA connectivity and 256 MB cache to handle continuous high-definition video streams. The drive supports systems with up to 64 cameras. It is suited for installers and businesses that need reliable always-on storage.
Check your recorder before ordering
Verify that your DVR or NVR accepts a 3.5 inch SATA hard drive and has a free drive bay. Confirm the recorder’s maximum supported capacity per bay. Ensure the system firmware can address a 12 TB volume. AllFrame technology works with compatible recorders to reduce frame loss and pixelation.
Fits standard surveillance bays
The drive slides into a typical 3.5 inch drive bay and connects via a SATA data cable and SATA power connector. No extra adapter or mounting bracket is required beyond the recorder’s standard hardware. Its 24/7 workload rating frees the system from consumer-drive limitations. The three-year manufacturer warranty covers the drive in always-on operation.
