0B42266 WD Ultrastar DC HC330 10TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD for 24x7 RAID Storage with the 0B42266

The 0B42266 is a WD Ultrastar DC HC330 10TB internal 3.5in SATA hard drive engineered for predictable throughput and sustained duty cycles in enterprise DAS/NAS and RAID arrays. Built on CMR recording and a 7200RPM mechanical platform, the drive prioritises consistent write behaviour under rebuild and parity workloads, while the 256MB cache supports steady burst handling and queue management in mixed I/O profiles.

For systems engineers designing scalable storage tiers, the 0B42266 supports 4Kn/512e sector formats to align with modern OS and controller stacks, and integrates cleanly into standard SATA backplanes with a single connector interface. Reliability is reinforced through rotational vibration safeguards for multi-bay enclosures and an MTBF rating of 2.0M hours, helping maintain array stability as chassis density increases. Security is hardware-based, using SED encryption with Secure Erase support to simplify encrypted-at-rest compliance and decommissioning workflows without relying on host-side processing.

Why Choose the 0B42266?

The 0B42266 delivers a pragmatic capacity-per-bay profile for cost-controlled growth in RAID shelves, NAS nodes, and server storage pools where predictable CMR behaviour matters more than peak IOPS. Its vibration-tolerant design supports deployment in dense enclosures, while SED capabilities reduce operational risk for regulated data and standardised lifecycle handling at scale.

WD designs Ultrastar enterprise HDDs around measurable reliability, controlled firmware behaviour, and compatibility with data centre infrastructure standards, supporting continuous 24x7 operation in multi-drive environments that demand consistent acoustics, thermals, and serviceability.

Key Applications:

• RAID arrays and rebuild-prone parity volumes
• Enterprise NAS and departmental file services
• Server-based DAS capacity expansion
• Backup and retention repositories
• Encrypted data-at-rest storage tiers
