Pros & Use-Case Suitability
-
Designed for surveillance systems (e.g. NVRs / DVRs) which record continuously (24×7). The firmware supports stable video stream capture.
-
Good for setups with multiple cameras (up to 64) without dropping frames.
-
CMR is preferred in many video and NAS applications because it tends to handle writes more predictably under continuous load than SMR, especially with multiple streams.
-
The RV sensors help maintain performance in multi-bay enclosures by reducing vibration impact.
-
Lower RPM ( 5400) means lower noise, lower heat, lower power consumption, which is beneficial in always-on surveillance/NAS boxes.
Limitations / What to Watch Out For
-
Not designed for very high transactional workloads (like databases / many random small writes), but excellent for streaming large writes (video).
-
The performance (seek times, latency) will be inferior to 7200 RPM or SSDs for random access tasks. If you plan to use the drive for general PC storage (OS / apps) it may be less ideal.
-
Though rated for continuous use and decent durability, any mechanical HDD can fail; regular backups are essential, especially for video data you care about.
-
The “180 TB/year” workload is a guideline; if usage exceeds that significantly under harsh conditions (high temperature, vibration, etc.), lifespan may reduce.
-
Availability of features like Rescue Data Recovery Services may vary by country / region. Need to confirm for India.
