Enterprise Bundle – 4 Drives 64TB (4x16TB) WD Gold Enterprise SATA HDD – 7200 RPM, 512MB Cache, CMR, RAID 5/6 Ready This matched quad-pack of WD Gold 16TB enterprise hard drives delivers 64TB of raw capacity built for demanding, continuous-operation storage environments. Each drive offers 262MB/s sustained transfer speeds, a 512MB high-performance cache, and CMR recording technology — providing the consistency and compatibility that RAID controllers and enterprise storage systems depend on. Combined, the four drives carry a total workload rating of 2,200TB per year and a projected reliability of 2.5 million hours MTBF per drive. Furthermore, WD's exclusive Rotational Vibration Safeguard (RVS) and HelioSeal technology ensure sustained performance inside multi-drive enclosures around the clock. Every drive is backed by a 5-year limited warranty. 64TB Raw RAID 5/6 Ready CMR Recording 24/7 Operation HelioSeal 5-Year Warranty Total Raw Capacity 64TB 4 × 16TB drives Transfer Rate 262MB/s Per drive, sustained Combined Cache 2,048MB 512MB × 4 MTBF (per drive) 2.5M hrs Projected reliability Warranty 5 Years Per drive 4 Matched Drives 2,200TB Combined Workload / Year 600K Load/Unload Cycles Each 10^15 Bits per Non-Recoverable Error RAID Configuration Guide for 4 Drives Four drives open up three powerful RAID configurations. Therefore, you can choose the right balance of usable capacity, read/write performance, and fault tolerance for your specific deployment requirements. Best Performance RAID 10 ~32TB Usable capacity Mirrors two striped pairs for the highest combined read/write throughput alongside resilient fault tolerance. Ideal for high-IOPS applications such as databases, VM hosts, and active transaction logs. Tolerates 1–2 drive failures Best Capacity Balance RAID 5 ~48TB Usable capacity Distributes parity across all four drives, delivering a strong balance of usable storage, solid read performance, and single-drive fault tolerance. Well suited to file servers, backup targets, and general NAS workloads. Tolerates 1 drive failure Maximum Protection RAID 6 ~32TB Usable capacity Uses dual distributed parity to survive simultaneous failure of any two drives without data loss. Furthermore, this configuration is recommended for high-value archive storage and environments where rebuild windows are long. Tolerates 2 drive failures Usable capacity figures are approximate and will vary based on your RAID controller and filesystem overhead. Always verify with your specific controller and enclosure vendor. Why WD Gold is Built for Multi-Drive Environments Rotational Vibration Safeguard (RVS) In a four-drive enclosure, adjacent spinning discs generate constant mechanical vibration that degrades read/write accuracy on standard drives. WD Gold's dual-sensor RVS system measures and corrects for this in real time — a hardware-level advantage that matters most in exactly the dense deployments this bundle is designed for. CMR for Full RAID Compatibility Conventional Magnetic Recording ensures complete compatibility with all major RAID controllers, HBAs, and storage appliances. Unlike SMR drives, CMR delivers predictable, consistent write performance under sustained workloads — critical for RAID rebuild operations and continuous write-heavy applications that would stall on shingled drives. HelioSeal EAMR TSA At 16TB, WD Gold combines three advanced technologies: helium sealing reduces internal drag and lowers power draw; Energy-Assisted Magnetic Recording (EAMR) achieves higher areal density; and the Triple State Actuator (TSA) provides precise head positioning for consistent track alignment across extended operation cycles. Power Efficiency Across the Bundle HelioSeal technology keeps each drive running cooler and more efficiently than conventional air-filled alternatives. Consequently, a four-drive deployment consumes considerably less power and generates less heat than equivalent capacities built on older architectures — reducing both cooling overhead and long-term operating costs in data-centre and NAS environments. 26W Total Active (4 drives) 22.4W Total Idle (4 drives) 6.5W Per Drive Active 5.6W Per Drive Idle Technical Specifications General – Per Drive FeatureSpecification Capacity16TB Form Factor3.5-Inch InterfaceSATA 6Gb/s Recording TechnologyCMR – Conventional Magnetic Recording Buffer / Cache512MB Advanced FeaturesHelioSeal, EAMR, Triple State Actuator (TSA), Advanced Format 512e, RVS, 24×7 continuous operation Dimensions (W × D × H)101.6 × 147 × 26.1 mm Weight690g per drive OS CompatibilityWindows, Windows Server, Linux, macOS Compliant StandardsRoHS 2011/65/EU, CE, FCC, UKCA, UL, KC, RCM, VCCI, BSMI, TUV, CB-Scheme, ICES-003 Warranty5-Year Limited Warranty Performance – Per Drive FeatureSpecification Spindle Speed7200 RPM External Transfer Rate600MB/s (interface) Internal Data Rate262MB/s (sustained) Annual Workload RatingUp to 550TB per year Load / Unload Cycles600,000 Reliability – Per Drive FeatureSpecification MTBF (projected)2,500,000 hours Non-Recoverable Read Errors1 per 10¹⁵ bits read 24×7 OperationYes Power – Per Drive FeatureSpecification Active Power6.5W Idle Power5.6W Environmental – Per Drive FeatureSpecification Operating Temperature5°C to 60°C Storage Temperature-40°C to 70°C Shock Tolerance (operating)50g @ 2ms half-sine wave Shock Tolerance (non-operating)250g @ 2ms half-sine wave Bundle – Combined Totals Featurex4 Bundle (Combined) Total Raw Capacity64TB (4 × 16TB) Combined Cache2,048MB Combined Workload RatingUp to 2,200TB per year Total Active Power~26W Total Idle Power~22.4W RAID 10 Usable Capacity~32TB (1–2 drive fault tolerance) RAID 5 Usable Capacity~48TB (1 drive fault tolerance) RAID 6 Usable Capacity~32TB (2 drive fault tolerance) JBOD / Spanning~64TB (no redundancy) Ideal Use Cases for the x4 Bundle SMB File & Application Servers A four-drive WD Gold array in RAID 5 provides ~48TB of protected storage — more than sufficient for shared drives, user home directories, and application data in small and medium business environments with 24/7 uptime demands. 4-Bay NAS Enclosures Perfectly sized to fill a 4-bay NAS from brands such as Synology, QNAP, and similar. Moreover, the enterprise-grade CMR and workload ratings ensure these drives keep pace with the intensive read/write cycles common in NAS-hosted surveillance, backup, and media streaming workflows. Virtualisation & VM Storage RAID 10 across four WD Gold drives delivers the combined throughput and resilience that virtualisation hosts require. Additionally, the 262MB/s per-drive transfer rate and 512MB cache provide the low-latency access that virtual machine images and snapshots depend on for responsive performance.
