Western Digital WD10EURX 1TB 3.5" SATA 6.0Gb/s 64MB internal hard drive

1 TB AV-GP drive for video surveillance

The Western Digital WD10EURX is a 1 TB 3.5 inch SATA 6.0Gb/s internal hard drive built for continuous audio and video recording. It belongs to the AV-GP series and uses IntelliPower spindle speed with a 64 MB cache to sustain 24x7 streaming workloads. The bare drive includes SilkStream, IntelliSeek, IntelliPark and Preemptive Wear Leveling technologies.

Suited for DVR and NVR storage arrays

This drive fits digital video recorders and network video recorders that need high-capacity sequential write performance and quiet operation. It is not intended for primary operating-system boot drives or for workloads that demand low-latency random access such as database servers or gaming rigs. Buyers who need faster random I/O or solid-state endurance should consider a different storage class.

1 TB capacity with 64 MB buffer

The terabyte capacity holds weeks of multi-camera footage at typical surveillance bit-rates while the 64 MB cache absorbs bursty write streams. Advanced Format sectors and a 1 million hour MTBF rating provide headroom for long-term archival. The drive reaches its practical limit when concurrent high-bitrate streams exceed the sustained throughput of the SATA 6.0Gb/s interface or when the 25 bad-sector allowance noted in the supplier condition becomes a concern.
