Purpose-built video storage

The Western Digital AV-GP WD20EURS is a 2TB 3.5-inch internal hard drive designed for continuous recording in DVRs, NVRs and surveillance appliances. Its SATA 3.0Gb/s interface and 64MB cache support steady sequential writes across multiple video streams. The drive is sold new as a bare unit without cables or brackets.

Suits always-on recorders.

Installers configuring 24×7 camera systems or PVR/DVR boxes will benefit from the firmware tuned for long-duration streaming and quiet operation. Builders who need a primary operating-system drive or fast random I/O for databases or gaming should look at solid-state alternatives instead.

SATA 3.0Gb/s interface decides compatibility

The drive connects through a standard SATA 3.0Gb/s port and requires a matching data cable and power connector from the host system. Controllers limited to SATA 1.5Gb/s will operate at the lower speed, while systems without any SATA ports cannot use this drive at all.
