IBM / HGST Ultrastar 1.8TB 10,000 RPM 12Gb/s SAS 2.5-inch SFF HDD

IBM Part Number: 01NN114 | HGST Model: HUC101818CS4200 | HGST P/N: 0B31795

The IBM 01NN114 is a high-capacity, mission-critical hard drive based on the HGST Ultrastar C10K1800 series. This drive represents the pinnacle of 10K RPM mechanical drive technology, offering a massive 1.8TB capacity in a compact 2.5-inch form factor. With a 12Gb/s SAS interface and a large 128MB cache, it is designed for high-density servers and storage arrays that require a balance of high performance, high capacity, and enterprise-grade reliability.

• Capacity: 💾 1.8 TB (1800 GB)

• Interface: ⚡ SAS 12Gb/s (Dual Port)

• Rotation Speed: 🏎️ 10,000 RPM

• Cache: 🧠 128 MB

• Form Factor: 📏 2.5-inch SFF (15mm Z-Height)

• Sector Size: 📏 4Kn (4K Native)

• Seek Time: ⏱️ 3.3ms (Average)

• MTBF: 🕒 2,000,000 Hours

• Massive 10K Density: 1.8TB is the maximum capacity achieved for 10,000 RPM drives. This allows you to maximize storage density in small-form-factor (SFF) server chassis without dropping down to slower 7.2K midline drives.

• IBM Enterprise Validation: This drive carries the IBM FRU 01NN114, meaning it has been rigorously tested and carries specialized firmware for IBM Storwize systems and System x servers.

• 12Gb/s SAS Interface: Optimized for the latest generation of SAS-3 controllers, providing high data throughput and dual-port redundancy for "no-single-point-of-failure" configurations.

• Target Systems:

  • IBM / Lenovo Servers: System x, ThinkSystem, and IBM Power Systems.

  • IBM Storage: Storwize V3700, V5000, and V7000 series (ensure your tray matches).

  • General Enterprise Servers: Works in Dell PowerEdge, HPE ProLiant, and Cisco UCS servers with 12G SAS controllers.

• Ideal Workloads:

  • Tier-1 Storage: High-performance storage for active applications.

  • Data Analytics: Rapidly processing large sets of structured data.

  • 💡 4Kn Sector Size: This drive uses 4K Native (4Kn) sectors. Most modern Operating Systems (Windows Server 2012+, Linux, ESXi 6.7+) support this, but older legacy systems may not. Ensure your environment is 4K aware.

    💡 15mm Height: Like most high-capacity 2.5" SAS drives, this is 15mm thick. It will fit in standard server drive trays but is too thick for most standard laptop bays or ultra-slim enclosures.

    The IBM 01NN114 (HGST HUC101818CS4200) is the ultimate choice for those who need maximum capacity without sacrificing the speed of a 10K RPM drive.
