Description
The Dell D939R hard drive is a high-performance 2.5-inch SAS drive with a capacity of 500GB, engineered for demanding enterprise environments. Its SAS interface provides enhanced reliability, data integrity, and performance compared to SATA drives, making it suitable for mission-critical applications and servers that require continuous operation and robust data handling. The 6Gb/s transfer rate ensures rapid data throughput, minimizing bottlenecks in storage subsystems. Operating at a spindle speed of 7200 RPM, this drive strikes a balance between performance and power consumption. It offers faster access times and higher sequential read/write speeds than 5400 RPM drives, while remaining more power-efficient and generating less heat than 10000 or 15000 RPM drives. The 16MB buffer helps to improve performance by caching frequently accessed data, further optimizing read and write operations. Designed for hot-swappable bays in servers and storage arrays, the Dell D939R allows for drive replacement or addition without shutting down the system, ensuring maximum uptime and serviceability. Its 2.5-inch form factor makes it ideal for dense server configurations and blade systems where space is at a premium. This drive is a reliable choice for applications requiring consistent performance, data integrity, and high availability.
