0F30146

High-Capacity 3.5in Enterprise SATA HDD for datacenter bulk storage with the 0F30146

The 0F30146 is a WD Ultrastar DC HC520 12TB 3.5in 7200RPM SATA enterprise hard drive engineered for capacity tiers in servers and storage arrays where predictable throughput and sustained write behavior are required. Built on CMR media, the 0F30146 maintains stable performance under continuous 24x7 write and rebuild cycles typical of RAID groups, NAS, and SDS platforms.

Architecturally, the 0F30146 targets dense SATA backplanes and HBA-connected storage nodes, using a 256MB cache to smooth burst activity while keeping latency consistent for sequential and mixed I/O. The 512e sector format enables broad OS and hypervisor compatibility, while providing an integration path for 4Kn alignment through emulation. Encryption support on the 0F30146 supports security policies for data-at-rest in shared datacenter environments without changing the storage topology.

Why Choose the 0F30146?

The 0F30146 delivers a balanced density-to-power profile for large-scale capacity deployments, helping architects expand usable TB per rack while maintaining operational predictability. With enterprise reliability characteristics and a stated 2.5M hours MTBF, the 0F30146 fits build patterns where drive consistency, service life, and fleet manageability matter more than short-duration peak IOPS.

WD designs Ultrastar platforms with a focus on continuous-duty operation, controlled acoustics, and qualification practices aligned to modern data centre standards. This engineering approach helps the 0F30146 integrate cleanly into validated server and storage ecosystems that prioritize uptime, predictable thermals, and repeatable procurement.

Key Applications:

Capacity tier in RAID storage arrays
Backup and restore repositories
Archive and compliance retention
NAS and general-purpose file services
Software-defined storage nodes
