The HP 1.2 TB 10K SAS 2.5″ HDD is a server‑grade hard disk drive engineered for enterprise and data‑center environments. It delivers a balanced combination of high storage capacity, fast rotational speed, and robust SAS interface performance — ideal for mission‑critical workloads, virtualization, databases, and multi‑user systems. Designed to fit the 2.5″ Small Form Factor (SFF) bays in HP ProLiant and other HP server platforms, this drive supports hot‑swap/ hot‑plug capabilities, enabling maintenance or upgrades without powering down servers. 

Commercial and compatible configurations are offered under various HP part numbers, typically with digitally signed firmware and enterprise‑class reliability optimizations. 

Key Features

Performance & Interface

• High Capacity: 1.2 TB of storage space for large datasets and server workloads. 

• SAS Interface: Serial Attached SCSI (commonly 12 Gb/s) for fast and reliable data throughput between the drive and server controller. 

• 10,000 RPM Spindle Speed: Faster rotational speed than lower‑RPM drives delivers lower latency and quicker read/write access ideal for IO‑intensive applications. 

• Dual‑Port SAS (on many models): Provides redundant data paths for higher availability and fault tolerance. 

Enterprise‑Ready Reliability

• Designed for 24×7 Operation: Built to handle continuous workloads typical of enterprise environments. 

• Hot‑Swappable: Can be replaced or installed without shutting down the server (with compatible chassis/backplane). 

• Digitally Signed Firmware: Enhances compatibility and firmware integrity, especially for HP servers. 

• Mean Time Between Failures (MTBF): Typical enterprise designs target multi‑million‑hour reliability. 

Form Factor & Compatibility

• Form Factor: 2.5″ Small Form Factor (SFF) making it suitable for rack/tower servers with SFF bays. 

• SmartCarrier/SmartDrive Support: Often bundled with an HP SmartCarrier for easy serviceability in HP ProLiant systems. 

• Wide Server Support: Compatible with many HP ProLiant generations (e.g., Gen8/Gen9/Gen10) and other SAS‑capable storage arrays depending on controller support. 

Security & Efficiency

• Advanced Format/Sectoring: Some variants use a 512e or 512n format for compatibility with file systems and server controllers. 

• Efficient Small Form Factor: Enables higher storage density per rack unit, lowering overall footprint and energy use. 

• Optional Encryption: Certain models support self‑encrypting drive (SED) features to protect sensitive data.
