Enterprise storage drive

The Western Digital WD1003FBYX-20PK is a 1TB 3.5" internal hard drive built for enterprise workloads. It spins at 7200 RPM with a 64MB cache and connects through a SATA 3.0Gb/s interface. The pack contains twenty bare drives intended for RAID arrays and continuous operation.

Suited for RAID deployments

Drives include RAID-specific firmware with time-limited error recovery (TLER) and a 1.2 million hour rating at 100% duty cycle. NoTouch ramp load technology protects the recording surface during constant 24x7 use. Builders who need a different interface or a single retail unit should look elsewhere.

SATA 3.0Gb/s interface

The drive communicates over SATA 3.0Gb/s, so the host controller or backplane must provide that exact connection. Compatibility depends on matching this interface; no other transport is supported by the hardware.

Domande su questo articolo

Does the 20PK pack include cables or mounting hardware for the bare drives?

The 20PK contains twenty bare drives only; SATA data cables, power cables and mounting screws must be sourced separately.

Should I choose the 1TB RE4 model or a different capacity for a RAID array?

The 1TB RE4 with 64MB cache and TLER is built for 24x7 RAID duty; select higher-capacity RE4 drives only if you need more space per bay.

How does the 1.2 million hour MTBF at 100% duty cycle translate to real-world RAID uptime?

The 1.2 million hour rating at 100% duty cycle reflects continuous 24x7 enterprise RAID operation with TLER and NoTouch ramp load technology.
