Product Details

16TB High-Capacity NAS Storage — CMR hard drive designed for medium to large-scale NAS systems up to 24 bays 7200 RPM | SATA III 6Gb/s — High spindle speed for fast data access and strong throughput in multi-user NAS environments NASware 3.0 Technology — Advanced firmware for seamless NAS integration, RAID compatibility, error recovery, and optimized performance CMR (Conventional Magnetic Recording) — Reliable, consistent performance in RAID 0/1/5/6/10 and ZFS arrays without SMR limitations Multi-Axis Shock Sensor — Detects subtle shock events and adjusts read-write operations to protect data in 24-bay environments 3D Active Balance Plus — Dual-plane balance control reduces vibration, noise, and performance degradation in multi-drive NAS chassis 550TB/Year Workload Rating — Enterprise-grade endurance rated for 24/7 always-on NAS and RAID operation 5-Year Limited Warranty — Extended warranty coverage for peace of mind in business-critical NAS deployments The WD Red Pro is Western Digital’s NAS hard drive built specifically for medium to large business NAS deployments with up to 24 drive bays. At 16TB with 7200 RPM spindle speed, it delivers the throughput and capacity needed for high-intensity workloads — file archiving, large-scale sharing, RAID array rebuilding, and continuous 24/7 operation. NASware 3.0 firmware optimizes every aspect of NAS integration: compatibility, RAID error recovery, vibration tolerance, and performance tuning for multi-bay enclosures.CMR recording technology ensures stable, predictable write performance in RAID configurations and extended file systems such as ZFS — unlike SMR drives which can stall during RAID rebuilds. The multi-axis shock sensor and Dynamic Fly Height technology work together to protect data integrity in large 24-bay chassis where mechanical vibration from adjacent drives is a constant factor. Every drive ships with extended thermal cycle burn-in testing for verified reliability before deployment.Ideal For Medium to Large Business NAS — Up to 24-bay NAS systems for enterprise-scale file storage and sharing RAID & ZFS Arrays — CMR for reliable RAID 0/1/5/6/10 and ZFS array performance and rebuild times High-Capacity Archive Storage — 16TB per drive for cost-effective large-scale data archiving and retention 24/7 Business-Critical NAS — 550TB/year workload rating and 5-year warranty for always-on environments Multi-Bay Vibration Environments — Shock sensor and 3D Active Balance Plus for 8–24 bay enclosures Specifications Model — WD Red Pro MPN — WD161KFGX SKU — CCWD161KFGX Capacity — 16TB Form Factor — 3.5" Interface — SATA III 6Gb/s Spindle Speed — 7200 RPM Cache — 512MB Recording Technology — CMR Max NAS Bays — Up to 24 Workload Rating — 550TB/year 24/7 Rated — Yes Warranty — 5-year limited
