MDD MAXDIGITALDATA 500GB 3.5" SATA Surveillance HDD

This renewed MDD MAXDIGITALDATA 500GB 3.5" SATA hard drive is built for always-on environments like CCTV DVRs and networked recorders. With a 5900RPM spindle, 16MB cache and SATA 3.0Gb/s interface, it balances steady data throughput with energy efficiency and whisper-quiet acoustics. The drive uses perpendicular recording and advanced error-correction to maintain reliability under constant write cycles typical of surveillance workloads.

How does this drive handle continuous recording in surveillance systems?

The MDD MAXDIGITALDATA 500GB is tuned for 24×7 operation—its firmware and mechanical design prioritize sustained write performance and durability. It provides stable data transfer rates and built-in diagnostics to reduce dropped frames and unexpected failures.

• Designed for continuous-duty surveillance DVR and NVR systems
• 78 MB/s maximum sustained transfer supports multiple camera streams
• Directed Offline scan and Clean Sweep calibration for ongoing health checks
• Enhanced G-force protection reduces handling and vibration damage

Will this drive work in my desktop PC or DVR, and what connectors are required?

This is a standard 3.5-inch internal SATA hard drive compatible with most desktops, dedicated DVRs and surveillance recorders that accept SATA 3.0Gb/s devices. Installation is straightforward but remember the drive ships as a bare unit without mounting screws or cables.

• 3.5" form factor fits desktop bays and many DVR/NVR chassis
• SATA 3.0Gb/s interface backward-compatible with common SATA controllers
• Requires system formatting before first use—format in your recorder/OS
• No accessories included: provide your own screws and SATA/power cables

What performance and protection features help preserve recorded footage?

Performance comes from a balance of rotational speed, cache and recording technology: 5900RPM and a 16MB buffer smooth burst and sequential writes typical of camera footage. Protective features and recording-head technologies reduce read/write errors and improve longevity under heavy-duty workloads.

• Perpendicular and TMR head technologies increase storage density and reliability
• 16MB cache and EPRML algorithms improve sustained write efficiency
• Native Command Queuing optimizes command ordering during high demand
• RoHS compliant design and on-the-fly error-correction for data integrity

How quiet and power-efficient is this HDD for continuous operation?

The drive is engineered for lower power draw and reduced acoustics compared with high-RPM desktop models, making it suitable for installations where heat and noise matter. That design helps limit thermal stress while keeping operating costs down in multi-drive arrays.

• 5900RPM reduces power consumption relative to 7200RPM drives
• Low-noise mechanics for quieter DVR rooms or home recordings
• Optimized for sustained operation to minimize thermal and energy strain
• Enhanced protection against shocks and vibration in multi-bay setups

Who is this for? The MDD MAXDIGITALDATA 500GB surveillance hard drive is aimed at buyers who need an affordable, reliable internal drive for constant video recording: CCTV integrators, small-business surveillance installations, DIY home security, and desktop users who want a quiet, low-power storage option. Note that this is a renewed bare drive sold without mounting hardware—ensure compatibility with your system and format the disk before use.
