Hewlett Packard Office 2.5-Inch 300 GB SCSI Hot-Swap Hard Drive 785067-B21

Overview of the Hewlett Packard Office 2.5-Inch 300 GB SCSI Hot‑Swap Hard Drive (785067-B21)

The HP 300 GB 10K 12G SAS 2.5‑inch drive is engineered for high‑performance server environments that demand reliable, hot‑swappable storage. Designed to fit seamlessly into HP ProLiant and other enterprise servers, this unit delivers a balanced combination of capacity, speed, and durability.

Key Technical Specifications

• Capacity: 300 GB (approx. 274 GB usable)
• Form Factor: 2.5‑inch (6.4 cm) SFF (Small Form Factor)
• Interface: SAS 12 Gb/s, compatible with SCSI command sets
• Rotation Speed: 10,000 RPM for rapid data access
• Cache: 8 MB write‑back cache (configurable)
• Hot‑Swap Capability: Yes – supports uninterrupted operation during drive replacement
• SmartDrive Carrier: Integrated HP SmartDrive carrier for secure mounting and power delivery
• Operating Temperature: 0 °C to +70 °C (standard data‑center range)
• Power Consumption: Typical idle: 3.5 W; active: 6.8 W (typical values for 10K drives)

Performance Highlights

The drive’s 12 Gb/s SAS interface ensures high throughput, enabling sustained sequential read/write speeds of up to 200 MB/s. Random I/O performance is equally impressive, with average latency around 4.5 ms for 4 KB reads and 6.0 ms for writes at 10K RPM.

Reliability & Endurance

Built on HP’s proven enterprise architecture, the drive incorporates advanced error‑correction codes (ECC) and SMART monitoring to detect and mitigate potential failures early. The 10-year limited warranty period (not included in this article) reflects confidence in its long‑term reliability.

Hot‑Swap Design & Integration

The hot‑swap feature is facilitated by the HP SmartDrive carrier, which provides a secure mounting mechanism and power/logic connections. This design allows administrators to replace or upgrade drives without shutting down the server, minimizing downtime in critical applications such as databases, virtualization hosts, and high‑availability clusters.

Compatibility & Ecosystem

This unit is fully compatible with HP ProLiant Gen8 and Gen9 servers, as well as other enterprise platforms that support 2.5‑inch SAS drives. It can be deployed in RAID configurations (RAID 0/1/5/6/10) or used as a standalone storage device for file servers, backup appliances, or high‑performance compute nodes.

Installation & Configuration Tips

• Mounting: Slide the drive into the designated bay until it clicks into place; ensure the SmartDrive carrier is properly seated.
• Power Management: Verify that the server’s power supply and controller support hot‑swap operations before initiating a replacement.
• Firmware Updates: Keep the drive firmware current via HP’s management tools to benefit from performance optimizations and bug fixes.
• RAID Configuration: When adding to an existing RAID array, use the server’s storage manager to resync or rebuild as needed; this process may take several hours depending on array size.

Use Cases & Deployment Scenarios

The 300 GB capacity makes it ideal for:

• Virtual Machine Hosts: Providing fast local storage for VMs that require quick access to disk I/O.
• Database Servers: Supporting transactional workloads where low latency is critical.
• Backup & Archive Appliances: Acting as a high‑speed staging area before data is moved to tape or cloud storage.
• High‑Performance Computing (HPC): Delivering rapid data throughput for scientific simulations and large dataset processing.

Environmental & Power Considerations

The drive’s power consumption aligns with modern data‑center efficiency standards. Its low idle power draw helps reduce overall energy usage, while the 10K RPM operation ensures that performance is not compromised when workloads spike.

Conclusion

The Hewlett Packard Office 2.5-Inch 300 GB SCSI Hot‑Swap Hard Drive (785067-B21) exemplifies enterprise storage excellence. With its robust SAS interface, rapid rotation speed, and hot‑swap capability, it delivers the reliability and performance required for mission‑critical applications in today’s demanding IT environments.
