Performance Metrics

Overview of the HPE 652749-B21 1TB SAS 6GBPS HDD

The HPE 652749-B21 1TB SAS 6GBPS SFF SC 7.2K RPM Midline Hard Drive represents a reliable enterprise-grade storage solution designed for small form factor servers and storage arrays. This drive is engineered to deliver consistent performance, durability, and scalability for businesses that require dependable midline storage capacity. With a 1TB capacity, 6Gbps SAS interface, and 7.2K RPM rotational speed, it balances affordability with enterprise-level reliability, making it suitable for a wide range of applications including backup, archiving, and general-purpose workloads.

Capacity 1TB

The drive offers 1TB of storage capacity, which is ideal for midline workloads where large-scale data storage is required without the premium cost of high-performance drives. The SAS 6Gbps interface ensures faster data transfer rates compared to SATA alternatives, providing improved reliability and dual-port connectivity for enterprise environments. This interface is particularly beneficial in scenarios where high availability and redundancy are critical.

Enhanced Reliability

SAS drives, including the HPE 652749-B21, are built with enterprise-grade reliability standards. Compared to SATA drives, SAS drives offer better error correction, improved signal integrity, and dual-port connectivity. These features make SAS drives more suitable for mission-critical environments where downtime or data loss can have significant consequences.

Scalability and Flexibility

SAS midline drives provide scalability options that SATA drives cannot match. With dual-port connectivity, they can be integrated into complex storage architectures, including redundant paths and failover configurations. This ensures that businesses can scale their storage infrastructure without compromising reliability or performance.

Hot-Swap Capability

One of the key features of the HPE 652749-B21 is its hot-swap capability. This allows administrators to replace or upgrade drives without shutting down the system, minimizing downtime and ensuring continuous availability. Hot-swap functionality is essential in enterprise environments where uptime is critical.

Smart Carrier Technology

HPE Smart Carrier technology enhances the manageability of the drive by providing visual indicators for drive status, activity, and health. This simplifies maintenance tasks and reduces the risk of errors during drive replacement or upgrades. Smart Carrier integration also ensures that drives are securely installed and properly recognized by the system.

Energy Efficiency

The 7.2K RPM rotational speed of the HPE 652749-B21 contributes to energy efficiency compared to higher RPM drives. This makes it suitable for organizations that prioritize reducing power consumption and cooling costs while maintaining reliable storage capacity. Energy-efficient drives help businesses achieve sustainability goals without compromising performance.

Interface: SAS 6GBPS

SAS Midline vs. SAS Enterprise Drives

SAS enterprise drives typically operate at higher rotational speeds (10K or 15K RPM) and are designed for mission-critical workloads requiring maximum performance. In contrast, SAS midline drives like the HPE 652749-B21 prioritize capacity and reliability at a lower cost. While enterprise drives are ideal for transactional databases and high-speed applications, midline drives are better suited for backup, archiving, and secondary storage.

SAS Midline vs. SATA Midline Drives

SATA midline drives offer cost-effective storage solutions but lack the advanced reliability and dual-port connectivity of SAS drives. The HPE 652749-B21 provides superior integration, error correction, and scalability compared to SATA alternatives. For businesses that require enterprise-grade reliability without the premium cost of high-performance drives, SAS midline drives are the preferred choice.

SAS Midline vs. Solid State Drives (SSD)

Solid State Drives deliver superior performance and lower latency compared to spinning hard drives. However, SSDs are significantly more expensive per gigabyte. The HPE 652749-B21 offers a cost-effective solution for workloads where capacity and reliability are more important than speed. Many organizations adopt a hybrid approach, using SSDs for primary storage and SAS midline drives for secondary or archival storage.
