WD Purple 3.5" 4TB, 128MB, SATA III Hard Drive, for Surveillance

The WD Purple 4TB is an internal hard drive engineered specifically for the demands of surveillance systems. Its 3.5-inch form factor is standard for desktop and NVR/DVR enclosures, ensuring broad compatibility. The drive is built to operate continuously, handling the constant data-writing tasks from multiple high-definition security cameras. This focus on write-intensive performance and reliability makes it a suitable component for modern security installations that require non-stop recording.

This model is equipped with a 128 MB cache to help manage data flow and prevent frame loss during simultaneous recording streams. It has a workload rating of up to 180 TB per year, a specification that reflects its mechanical durability in high-transaction environments. The drive also integrates S.M.A.R.T. technology, allowing the host system to monitor its operational health and anticipate potential issues. Its fundamental design for 24/7 operation is a key attribute for applications where system uptime is critical.
