Best and Most Reliable Hard Drive Brand for CCTV Recorder?

tony79 on 13/12/2021 - 18:01

Hi there,

I must have burnt through about 3 WD Purple CCTV HDD's over the past few years in my CCTV system. They just don't seem to last? Is that normal? How have others gone with HDD's used for CCTV recorders? And what brands have you had good experiences with?

Thanks

    Which recorder unit do u use? How many cameras.

      Some of the NVR's spec an input bandwidth as the camera's do compression and the amount of data written depends on the amount of data changing in the camera's area that it recording. Also depends on the compression used MPEG2 is crap compared to H264 or the better H265 (there are many other codec's that are bad and others that are good).

    How was WD or the retailer with replacing them?
    What was the WD model of the HDD?

    They are surveillance HDD, not CCTV HDD. I need to find/spec some surveillance HDD's (max 6TB) for a replacement HikVision NVR in the next few weeks.

      What? CCTV IS surveillance. There is no difference in function, let alone HDD specs

    I've experienced the same with WD purple about 3-4 years of 24/7 use on continuous recording with AI Logging. All my builds are now using WD Red which are constantly reliable.

    The workload of purples arent that great :

    As used for storage capacity, 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.
    Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.
    MTBF specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions: workload of 90TB/year and drive temperature of 40°C. Derating of MTBF will occur above these parameters, up to 65°C drive temperature. MTBF does not predict an individual drive’s reliability and does not constitute a warranty.
    For capacities 4TB and higher.

    If you want to use the latest technology in cctv, check this website out www.bolideco.com. They are professional surveillance products in the industry. Not sure if they do retail.
