IBM 1.2TB 10K RPM SAS 6Gb/s Enterprise Hard DriveModel: HUC101212CSS600 | IBM PN: 85Y6155 | HGST PN: 0B28475 | 1.2TB Capacity | 10K RPM

The IBM 85Y6155 (manufactured by HGST as the Ultrastar C10K1200) is a high-capacity enterprise drive designed for high-density storage environments. This drive balances a massive 1.2TB capacity with the rapid data access of a 10,000 RPM spindle speed. Engineered for IBM System x and Storwize platforms, it offers the dual-port SAS reliability required for mission-critical data center applications.

📊 Technical Specifications

✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited, health-verified, and 100% surface tested. Each unit has been cleared of previous data and verified for mechanical stability to meet original IBM/HGST enterprise performance standards.

• IBM Certified Firmware: Carries genuine IBM firmware (85Y6155), ensuring seamless integration with IBM ServeRAID controllers and Storwize systems. This provides accurate health telemetry and prevents "unsupported drive" flags in management consoles.

• HGST Ultrastar Reliability: Built on the industry-leading HGST platform, known for superior head-positioning accuracy and mechanical durability in high-vibration, multi-drive environments.

• Large Storage Density: Provides a large 1.2TB footprint in a compact 2.5" form factor, allowing for high-capacity RAID arrays without sacrificing the performance of a 10K RPM motor.

• Native 512n Format: The 512-byte native sector format ensures 100% compatibility with older RAID controllers and legacy operating systems that do not support 4Kn or 512e "Advanced Format" drives.

📦 Compatibility & Use Case

• Target Systems: Optimized for IBM System x servers (x3550, x3650 M4/M5), IBM Storwize V3700/V5000/V7000, and PureFlex systems.

• Ideal Workloads: Tier-2 mission-critical storage, database hosting, virtualization (VMware/Hyper-V), and high-capacity enterprise boot volumes.

• Controller Note: ⚠️ Important: This is a SAS drive. It requires a SAS-capable backplane and controller. It will not function in a standard consumer laptop or desktop SATA port.
