0F22146 WD MegaScale DC 4000.B 4TB SATA 64 MB 3.5" Server HDD

Capacity-Oriented 3.5in Enterprise SATA HDD Tiering with the 0F22146 for Always-On Storage Nodes

The 0F22146 is a 3.5in WD/HGST MegaScale DC 4000.B enterprise HDD designed for nearline tiers where predictable throughput, sustained duty cycles, and cost-efficient capacity are the primary architectural drivers. In storage nodes that are CPU-agnostic but I/O-sensitive, the 0F22146 integrates cleanly behind modern server SATA controllers and RAID HBAs, aligning with common x86 platforms used for backup targets, object repositories, and content stores.

Using CMR media and a 4Kn (512e) sector format, the 0F22146 supports consistent write behavior that is easier to model in RAID groups than SMR alternatives, reducing rebuild risk and performance variance under mixed workloads. The SATA interface enables straightforward expansion through backplanes and JBOD enclosures, while the 5700 RPM design balances capacity density with steady-state power and acoustic profiles for high-drive-count chassis. This makes the 0F22146 well-suited to storage architectures where PCIe lanes are prioritized for networking or caching tiers, and bulk data resides on scalable HDD pools.

Why Choose the 0F22146?

The 0F22146 delivers a practical density-to-operational profile for 24x7 arrays, supporting predictable scaling by adding drives rather than redesigning the platform. For enterprise deployments, the 0F22146 helps standardize nearline HDD tiers across NAS, RAID, and object nodes, simplifying spares strategy and capacity planning while maintaining a stable mechanical footprint for serviceability.

WD engineers the MegaScale platform around continuous-operation reliability and data center integration, emphasizing consistent behavior in multi-drive environments and alignment with common enclosure, backplane, and RAID management standards used in enterprise storage stacks.

Key Applications:

• Nearline HDD storage tiers
• Backup-to-disk repositories
• Cold and warm data archives
• Object and content storage nodes
• 24x7 NAS/RAID arrays
