HP – 581286-B21 600GB SAS 6G 10K SFF Hard Drive
Description
The HP 581286-B21 is an enterprise-grade internal hard drive designed for server and storage systems. It delivers reliable performance for mission-critical workloads in data centers, virtualization, and database applications. The drive uses a Serial Attached SCSI (SAS) interface to provide high-speed data transfer and enterprise-class reliability. Its 10,000 RPM spindle speed supports low latency and rapid access times, while the 2.5-inch Small Form Factor (SFF) design enables higher storage density and efficient cooling in modern rack and blade systems. This hard drive is also hot-swappable, allowing replacement or upgrades without powering down the server.
Key Features
- 600GB Capacity – Suitable for business-critical applications and high-performance storage arrays.
- SAS 6 Gb/s Interface – High-speed enterprise data transfer protocol.
- 10,000 RPM Spindle Speed – Delivers low access latency and good I/O performance.
- 2.5-inch Small Form Factor (SFF) – Space-efficient design for dense server environments.
- Dual-Port SAS – Enables redundant data paths for improved fault tolerance.
- Hot-Swappable – Allows drive replacement without shutting down the server.
- 16 MB Cache – Helps smooth out data bursts and improve performance.
- Enterprise Reliability – Built for 24/7 operation in server workloads.
