WD Red Pro 6TB 7200RPM 256MB Cache SATA 6Gb/s 3.5" NAS HDD Hard Drive (WD6006FFBX)

The Western Digital WD Red® Pro 6TB internal hard drive (model WD6006FFBX) is an enterprise-class 3.5-inch hard drive engineered to power high-capacity Network Attached Storage (NAS) racks, multi-bay business RAID arrays, and AI-accelerated storage systems (AI NAS). Built to sustain heavy, continuous 24x7 multi-client workloads, it utilizes Conventional Magnetic Recording (CMR) technology to prevent write performance bottlenecks during continuous array operations. Featuring a 7200 RPM rotational spindle speed, a 256MB cache, and a SATA 6Gb/s interface, the drive achieves sustained sequential data transfer rates up to 238MB/s. The WD6006FFBX incorporates Western Digital's NASware™, OptiNAND™, and ArmorCache™ architectures alongside Time-Limited Error Recovery (TLER) firmware controls, ensuring maximum uptime and preventing drive dropouts in RAID groups. Engineered for demanding endurance with an annual workload rating of 550TB/year and a mean time between failures (MTBF) of up to 2.5 million hours, the drive is qualified for deployments with unlimited drive bays and is backed by a 5-year limited manufacturer warranty.

Key Features

• Conventional Magnetic Recording (CMR): Delivers sustained, dependable write throughput essential for large-scale multi-user data aggregation and uninterrupted RAID rebuilds.
• Engineered for Unlimited Drive Bay Deployments: Fully balanced and vibration-tolerant for seamless operation across desktop towers and high-density rackmount enterprise NAS enclosures.
• Up to 238MB/s Transfer Rate & 7200 RPM: Fast rotational performance combined with a 256MB cache delivers data transfer rates up to 238MB/s for quick multi-stream access.
• NASware™, OptiNAND™ & ArmorCache™ Integration: Hardware and firmware optimizations that improve system compatibility, leverage embedded flash for metadata efficiency, and protect write cache data during power drop events.
• RAID-Optimized Time-Limited Error Recovery (TLER): Proactively prevents the storage controller from dropping healthy drives from RAID sets due to extended drive-level error recovery processes.
• Heavy Workload Durability (550TB/year): High endurance rating designed to handle the heavy read/write demands of concurrent multi-user enterprise environments around the clock.
• Enterprise Reliability (Up to 2.5M Hours MTBF): Engineered to demanding enterprise hardware tolerances for continuous operation in mission-critical storage systems.
• 5-Year Limited Manufacturer Warranty: Comprehensive enterprise coverage for professional and commercial applications.
