MaxDigitalData MDD24TS51272DVR 24TB 7200RPM 512MB Cache SATA 6.0Gb/s 3.5" internal hard drive

24 TB SATA surveillance drive

The MaxDigitalData MDD24TS51272DVR is a 3.5 inch internal hard drive built for continuous video recording. It targets installers and system integrators who need a single high-capacity spindle for CCTV DVR and NVR appliances. The drive ships as a bare unit without screws or cables and requires formatting before the host system will recognise it.

Capacity headroom and throughput limits

Twenty-four terabytes can hold roughly twenty-four thousand hours of high-definition footage depending on the recorder's bit-rate settings. A 7200 RPM spindle and 512 MB cache keep sustained write streams smooth during multi-camera capture. The SATA 6.0 Gb/s interface caps peak transfer speed, so very high-channel-count or ultra-high-resolution deployments may saturate the bus before the platters do.

Upgrade path from smaller surveillance spindles

The drive replaces lower-capacity 3.5 inch SATA drives in existing DVR, NVR, NAS or desktop chassis that accept a 26.10 mm z-height. The jump is worthwhile when retention policies demand weeks of footage on a single volume or when reducing drive count simplifies RAID rebuilds. Systems limited to smaller maximum drive sizes or older SATA controllers will not benefit.
