HDD HPE 900 GB 2,5 inch SAS 10000 tpm 721747-001

The HPE 900 GB 2.5" SAS 10000 RPM drive (Hewlett Packard Enterprise 721747-001) is a 2.5-inch enterprise-class hard disk designed for server and storage systems that require a balance of capacity, speed and reliability. With 900 GB of formatted capacity and a 10,000 RPM spindle speed on a Serial Attached SCSI (SAS) interface, this drive is intended for environments with frequent random read/write operations and mixed transactional workloads. It is compatible with many rack and blade servers that support 2.5" SAS drives and is intended for use in redundant and managed storage arrays.

Advantages

This HPE SAS HDD provides a combination of relatively high rotational speed and 2.5" form factor, offering faster access times and lower latency compared with lower RPM drives of the same capacity. The SAS interface ensures sustained throughput and enterprise-grade connectivity for RAID arrays and multi-path storage configurations. The compact 2.5" size helps increase drive density in server chassis and storage enclosures while maintaining predictable performance for database, virtualization and mixed application use.

Suitable for

• Database servers requiring frequent random I/O and consistent response times
• Virtualization hosts and hyper-converged infrastructure with mixed workloads
• RAID arrays and enterprise storage systems that use 2.5" SAS drives
• Backup and archive tiers where moderate capacity with faster access is needed

When it may not be suitable

This HDD may not be suitable for use cases that demand the highest sequential throughput or extremely low latency achievable with enterprise SSDs, such as high-frequency transaction processing or in-memory databases where flash storage is preferred. It may also be less appropriate when maximum capacity per bay is the priority, since larger-capacity 3.5" drives or high-capacity SSDs can offer greater raw storage density.

Key specifications

• Form factor: 2.5-inch
• Capacity: 900 GB
• Rotational speed: 10,000 RPM
• Interface: Serial Attached SCSI (SAS)
• Typical use case: enterprise server and storage deployments

How to use

Install the drive into a compatible 2.5" SAS bay or hot-swap tray in accordance with your server or storage enclosure manual. Configure the drive within your RAID controller or storage management software as part of an array or as a standalone volume depending on redundancy and performance requirements. Ensure firmware and controller drivers are up to date and monitor drive health through system management tools to detect early signs of wear or failure.

What to consider before purchase

• Compatibility with your server or storage controller's 2.5" SAS bays and supported drive models
• Required performance characteristics (random I/O, sequential throughput, latency) for your applications
• Desired redundancy level and RAID configuration to meet availability and rebuild time goals
• Whether enterprise SSDs are preferable for workloads demanding very low latency or very high IOPS

Recommendations

For balanced enterprise workloads, deploy this 900 GB 10K SAS drive in RAID configurations that match your availability and performance targets, keep firmware and monitoring tools current, and pair with appropriate caching or SSD tiers where additional IOPS or lower latency is required.
