⚡ Key Features

• Built for 24/7 video capture with a 180TB/year workload rating — the continuous write duty a DVR or NVR imposes.
• AllFrame firmware helps reduce frame loss and improve overall video playback in surveillance recorders.
• Handles up to 64 single-stream HD cameras from one drive, so a mid-size installation stays on a single spindle.
• 256MB cache buffers simultaneous camera streams and playback requests.
• CMR recording keeps write performance predictable as the drive overwrites the oldest footage.
• Up to 180MB/s sustained transfer for recording, review and export at the same time.
• Certified for enclosures with up to 16 drive bays, covering larger recorders and surveillance NAS units.
• Up to 1,000,000 hours MTBF and 300,000 load/unload cycles for equipment that never powers down.
• Modest 4.7W read / 4.3W write draw limits heat build-up inside a closed recorder chassis, backed by a 3-year limited warranty.
