Enterprise-grade storage drive

The Western Digital RE3 WD1002FBYS is a 1 TB 3.5-inch internal hard drive built for servers and storage arrays. It spins at 7200 RPM with a 32 MB cache and a SATA 3.0Gb/s interface. A dual-processor design delivers a 20% performance improvement over the previous generation.

Vibration-resistant integration

The drive fits a standard 3.5-inch bay and connects via SATA data and power cables. StableTrac secures the motor shaft at both ends to cut system-induced vibration. Fourth-generation RAFF technology monitors and corrects linear and rotational vibration in real time, yielding a 60% improvement in high-vibration environments over the previous generation. TLER limits error-recovery time to prevent drive fallout in RAID arrays.

Sustained workload behaviour

Average latency sits at 4.2 ms under continuous operation. The vibration-correction features maintain throughput when multiple drives share a chassis. Units are supplied as bare drives, erased to DoD 5220.22-M standard, and may show up to 25 bad sectors or cosmetic label differences. Not suited for buyers who need a formatted, partitioned volume out of the box or who require a newer interface than SATA 3.0Gb/s.
