Product Description
IBM ESF2 1.14TB 10K RPM SAS SFF-2 Disk Drive
The IBM ESF2 is a high-performance 1.14TB (1.146 TB raw) 10,000 RPM SAS hard disk drive in SFF-2 (2.5-inch small form factor with Gen2 carrier) format. Featuring native 4224-byte (4K) sectors, SAS 12 Gb/s interface, and optimized for demanding workloads, this drive provides cost-effective, reliable bulk storage. It serves as a standard high-capacity option for IBM Power Systems environments requiring efficient data handling without SSD-level performance needs.
Key Features
- 1.1TB capacity (marketed; 1.146 TB actual) at 10,000 RPM for balanced speed and density.
- SAS 12 Gb/s interface for high throughput and compatibility.
- Native 4K (4224-byte) sector formatting, required for current IBM i releases.
- SFF-2 2.5-inch carrier for hot-plug installation in compatible bays.
- Designed for RAID-5, RAID-6, or RAID-10 arrays in Power Systems servers.
- Proven reliability for expanding storage pools or replacing drives.

Benefits
This drive delivers excellent value for high-capacity storage in IBM Power Systems setups. The 10K RPM speed offers strong performance for mixed workloads, while the native 4K sectors ensure optimal compatibility and efficiency on modern servers running IBM i, AIX, or Linux. It supports seamless expansion of existing arrays, cost-effective bulk data storage, and reliable operation in environments prioritizing capacity over maximum IOPS. The design reduces total ownership costs through high density and proven IBM engineering.
Compatibility
The IBM ESF2 disk drive is compatible with IBM Power Systems servers featuring SAS bays or controllers, including Power8, Power9, Power10, and Power11 generations. It works in systems running IBM i, AIX, or Linux, particularly where 4K sector formatting is required for IBM i. Supported in internal system unit bays and EXP24S/EXP24SX drawers with appropriate backplanes. Ideal for configurations needing high-performance HDDs in RAID setups or as economical storage expansions.
