WD Purple Surveillance Hard Drive – 2 TB, 64 MB, 5400 rpm, WD22PURZ

The Right Drive for the Right Job. WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility with a wide range of security systems, and some of our latest models (WD22PURZ, WD42PURZ, and WD63PURZ) have improved power efficiency. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.

Product Specs

• Engineered specifically for mainstream surveillance systems.
• AllFrame technology delivers optimizations for write-intensive, low-bit-rate, high stream-count workloads typical to mainstream surveillance applications.
• Supports up to 180 TB/yr workload rate². | ²Workload Rate is defined as the amount of user data transferred to or from the hard drive. The workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). The workload Rate will vary depending on your hardware and software components and configurations.
• 1TB¹ through 3TB support up to eight bays; 4TB and above support up to 16 bays and employ tarnish-resistant components for harsher environments.
• ¹As used for storage capacity, 1TB = one trillion bytes. Actual user capacity may be less, depending on the operating environment.
