WUH722020BLE604 – 20TB 7200 RPM SATA 6Gb/s 3.5-Inch Ultrastar He20 Enterprise Hard Drive
The Western Digital Ultrastar He20 WUH722020BLE604 is a 20TB helium-filled enterprise hard drive aimed at hyperscale and data-center buyers building high-density storage. Its 7200 RPM spindle and 550 TB/year workload rating make it a fit for capacity-tier object storage, backup targets, and large-scale NAS/enterprise arrays where predictable sequential performance matters more than flash-level latency. Note that as a SATA 6 Gb/s device, throughput is bounded by the interface, so buyers needing higher transfer ceilings may evaluate the SAS variants in the same family.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model | WUH722020BLE604 |
| Series | Ultrastar He20 (WD’s enterprise-capacity helium platform) |
| Capacity | 20 Terabytes (TB) |
| Interface | SATA 6 Gb/s |
| Form Factor | 3.5-inch |
| Spindle Speed | 7200 RPM |
| Cache | 256 MB |
| MTBF | 2.5 million hours (vendor-rated reliability figure) |
| Workload Rating | Up to 550 TB/year |
| Enclosure | Helium-sealed design — reduces friction and heat for enhanced efficiency |
| Power Consumption | Low power draw suitable for large-scale deployments (actual draw varies by operating mode) |
Good to know
- Compatibility: standard 3.5-inch SATA 6 Gb/s drive bay; confirm your backplane and HBA support high-capacity (>16TB-class) drives before rollout.
- Family positioning: the Ultrastar He20 line sits in WD’s enterprise-capacity tier, above NAS-oriented offerings such as IronWolf-class products, and complements SAS-interface Ultrastar variants for customers who need the higher bandwidth of that protocol.
- Buying tip: verify the exact model string (WUH722020BLE604) on your quotation, as Ultrastar drives ship in multiple interface and firmware configurations that are not interchangeable in mixed fleets.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
