Internal hard drive HP P40432-S21 900 GB 15,000 RPM 2.5" SAS

HP P40432-S21 is a 2.5" internal enterprise-class hard drive with 900 GB capacity and a 15,000 RPM spindle speed. Designed for server and storage array environments, this SAS drive delivers low-latency, high-throughput performance suited to demanding transactional and random I/O workloads. The drive’s 2.5" form factor and enterprise-grade construction make it appropriate for dense server configurations where consistent performance and reliability are required.

Advantages

This internal hard drive provides high rotational speed and a SAS interface to improve response times for database, virtualization and transaction-heavy applications. Built for enterprise use, it offers a balance of capacity and performance in a compact 2.5" format, enabling higher drive density in racks and blade systems. The drive’s consistent spindle speed and server-grade design contribute to predictable I/O behavior under sustained load.

Suitable for

• Database servers requiring fast random reads and writes
• Virtualization hosts and hyper-converged infrastructure
• Transactional applications and OLTP workloads
• High-performance storage arrays and tiered storage

Key specifications

• Capacity: 900 GB
• Form factor: 2.5 inch
• Spindle speed: 15,000 RPM
• Interface: SAS (high-throughput, low-latency serial attached SCSI)
• Weight: approx. 0.5 kg

How to use

Install the HP P40432-S21 into a compatible server or storage array bay that supports 2.5" SAS drives. Observe standard rack or chassis installation procedures: power down the host if hot-swap is not supported, secure the drive in the carrier or tray, connect the SAS interface and power, then power on the system. Initialize and format the drive in the operating system or storage controller according to your RAID or volume configuration and perform any required firmware or diagnostic checks before placing it into production.

Usage recommendations

Use this drive in enterprise environments where sustained random I/O performance is critical. Pair with a compatible controller supporting 12 Gbit/s SAS for optimal throughput, implement RAID or redundancy appropriate to your availability needs, and monitor drive health through server management tools. Ensure firmware is kept up to date via trusted vendor channels and follow manufacturer guidelines for ambient temperature and vibration limits to maintain reliability.
