Fit and application
Drops into any DVR or NVR chassis taking a standard 3.5" SATA drive, and works equally well in desktops, servers, NAS units and external enclosures. The 7200 RPM spec keeps write throughput steady under the sustained load of continuous multi-channel recording, which is the workload that kills consumer-grade drives sold for occasional use.
Configuration note for installers
Drives shipped for CCTV use arrive fitted and ready to record, but the recorder's own storage settings still determine behaviour once the disk fills. If a connected recorder — including Hikvision units — reports "Storage Full", check the Storage/HDD menu and enable Overwrite (loop recording) so the oldest footage is purged automatically instead of halting capture. This is a recorder-side setting, not a drive fault, and applies regardless of which NVR/DVR brand the drive is paired with.
Suitable for 24/7 continuous recording workloads where reliability under sustained write cycles matters more than peak burst speed.

Frequently Asked Questions
Is the ST500DM002 compatible with Hikvision recorders?
Yes — it works with Hikvision DVRs/NVRs, though Overwrite/loop recording must be enabled in the recorder's storage settings for continuous operation.
My recorder shows 'Storage Full' with this drive installed — is the drive faulty?
Usually not: this happens when Overwrite/loop recording isn't enabled in the recorder's HDD settings, so old footage isn't being deleted automatically.
What interface and cache does this drive use?
It uses a SATA III interface with a 128MB cache and spins at 7200 RPM.
Will this drive fit any DVR or NVR?
It's a standard 3.5-inch SATA drive, compatible with DVR and NVR systems as well as desktops, servers, NAS devices and external enclosures.
