80TB (5x16TB) WD Gold Enterprise SATA HDD 3.5″ 7200 RPM, 512MB Cache

Enterprise Bundle – 5 Drives 80TB (5x16TB) WD Gold Enterprise SATA HDD – 7200 RPM, 512MB Cache, CMR, RAID 5/6 Ready Step up to serious enterprise capacity with this matched set of five WD Gold 16TB hard drives — 80TB of raw, enterprise-grade storage ready to deploy straight into a RAID array or high-density NAS. Each drive delivers 262MB/s sustained transfer, a 512MB cache buffer, and CMR recording for predictable, controller-compatible writes. Across five drives the combined workload rating reaches 2,750TB per year, and each unit carries a projected 2.5 million hours MTBF. WD's Rotational Vibration Safeguard (RVS) dual-sensor system actively counteracts inter-drive vibration in multi-bay enclosures, while HelioSeal helium sealing keeps power draw low and operating temperatures stable at scale. Every drive is covered by a 5-year limited warranty. 80TB Raw RAID 5/6 Ready CMR Recording 24/7 Operation HelioSeal 5-Year Warranty Total Raw Capacity 80TB 5 × 16TB drives Transfer Rate 262MB/s Per drive, sustained Combined Cache 2,560MB 512MB × 5 MTBF (per drive) 2.5M hrs Projected reliability Warranty 5 Years Per drive 5 Matched Drives 2,750TB Combined Workload / Year 32.5W Total Active Power 600K Load/Unload Cycles Each How 80TB Stacks Up Across the Bundle Range The x5 bundle sits at the high end of the WD Gold 16TB range, offering substantially more usable capacity than smaller configurations while keeping power and cost per terabyte efficient. Moreover, five drives unlock RAID 6 double-parity protection without sacrificing too much usable space. Raw Capacity Comparison – WD Gold 16TB Bundle Range x1 Single 16TB x2 Bundle 32TB x4 Bundle 64TB x5 Bundle 80TB x6 Bundle 96TB RAID Configuration Guide for 5 Drives Five drives support three distinct RAID configurations. Consequently, you can optimise your array specifically for throughput, balanced capacity, or maximum fault tolerance depending on the criticality of your data. Best Capacity Balance RAID 5 ~64TB Usable capacity Parity is distributed across all five drives, yielding the best usable-to-raw ratio in this configuration. Ideal for file servers, media libraries, and NAS workloads where strong capacity utilisation matters alongside single-drive resilience. Tolerates 1 drive failure Maximum Protection RAID 6 ~48TB Usable capacity Dual distributed parity protects against simultaneous failure of any two drives. Furthermore, the extra parity overhead is proportionally smaller at five drives than at four — making this configuration an efficient choice for critical, long-retention archives and compliance storage. Tolerates 2 drive failures Maximum Throughput RAID 50 ~64TB Usable capacity (typical split) Combines RAID 5 striping across sub-groups for dramatically higher sequential and random read throughput than a single RAID 5 set. Additionally, a nested configuration improves rebuild performance — reducing the vulnerability window after a drive replacement. Tolerates 1 drive per sub-group Usable capacity figures are approximate and will vary based on RAID controller implementation and filesystem overhead. Always confirm with your specific enclosure vendor before deployment. Enterprise Technology Purpose-Built for Dense Arrays RVS – Critical at Five Drives Five spinning platters in a single enclosure generate significant cross-drive vibration. WD Gold's dual-sensor Rotational Vibration Safeguard measures and corrects for this interference continuously at the hardware level — maintaining accurate head positioning and consistent read/write performance even as the array runs under sustained load, day after day. CMR – Reliable RAID Rebuilds When a drive in a large array fails, the rebuild process writes hundreds of terabytes sequentially. CMR recording handles sustained sequential writes consistently — unlike SMR, which throttles during extended write operations. As a result, rebuild times remain predictable and the remaining drives are not left exposed for longer than necessary. HelioSeal EAMR TSA The three-layer advanced engineering behind WD Gold 16TB: helium sealing cuts internal turbulence and reduces power draw at scale; Energy-Assisted Magnetic Recording achieves high areal density without sacrificing write endurance; and the Triple State Actuator ensures precise head positioning across millions of seek cycles. Power at Scale – 5-Drive Total HelioSeal technology keeps each drive running cooler and drawing less power than air-filled alternatives of comparable capacity. Therefore, operating five WD Gold drives continuously is more energy-efficient than running five conventional high-capacity air-filled drives — reducing cooling overhead and energy costs in NAS and server enclosures over the long term. 32.5W Total Active (5 drives) 28W Total Idle (5 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 Featurex5 Bundle (Combined) Total Raw Capacity80TB (5 × 16TB) Combined Cache2,560MB Combined Workload RatingUp to 2,750TB per year Total Active Power~32.5W Total Idle Power~28W RAID 5 Usable Capacity~64TB (1 drive fault tolerance) RAID 6 Usable Capacity~48TB (2 drive fault tolerance) RAID 50 Usable Capacity~64TB (1 drive per sub-group) JBOD / Spanning~80TB (no redundancy) Ideal Use Cases for the x5 Bundle 5-Bay NAS Enclosures Sized precisely for popular 5-bay NAS units from Synology, QNAP, and Terramaster. RAID 5 across all five drives delivers ~64TB of protected shared storage — more than enough for SMB file sharing, media serving, and multi-user backup simultaneously without sacrificing redundancy. High-Capacity Archive & Compliance Storage RAID 6 with five drives provides ~48TB of dual-parity protected storage — an excellent configuration for long-term archives, regulated data retention, and surveillance footage storage where simultaneous drive failure must be tolerated without data loss. Media Production & Post Houses Professional video editors and post-production teams benefit from the high sequential throughput available across five enterprise drives. Furthermore, the 262MB/s per-drive sustained rate supports direct editing of high-bitrate footage and concurrent multi-user access across shared project storage.
