HPE - 431935-B21 - HP 72GB 15K rpm, 2.5" SFF SP SAS hard drive

The HPE 431935-B21 is a refurbished HP 72GB 15K RPM 2.5-inch SFF SAS hard drive designed for enterprise server and storage environments where low-latency I/O and consistent performance matter. With its 15K spindle speed, SAS interface, and Small Form Factor (SFF) design, it is well suited for OS volumes, logs, and read/write-intensive application tiers in data centers and remote sites.

This drive is commonly deployed in HPE ProLiant SFF drive bays and works well in arrays managed by RAID CONTROLLER options for redundancy and simplified administration. If you are standardising spares across your fleet, you can also browse related refurbished platforms and components in HPE. For alternative performance profiles and lower latency, consider mixing tiers with SSD where appropriate.

Key Features

Key technical characteristics for integration into existing HPE SFF SAS infrastructures:

• 72GB capacity in a 2.5-inch SFF form factor to fit dense ProLiant SFF drive bays and compact storage shelves.
• 15K RPM spindle speed to reduce access times for transactional workloads and boot/application volumes.
• SAS interface to support enterprise backplanes and dual-path capable storage designs where applicable.
• HP/HPE server drive option (431935-B21) to help maintain configuration consistency across installed HPE environments.
• Compatible with HPE ProLiant SFF SAS platforms and drive cages, for example ProLiant DL360/DL380 (SFF configurations) and other HPE SFF SAS server families.
• Designed for use in RAID arrays to support availability-focused configurations such as mirrored OS volumes or multi-drive data sets.
• Optimised for 24/7 enterprise operation to support continuous workloads in data center and edge deployments.
• Suitable as a replacement/spare drive in existing HPE SAS storage pools to reduce downtime during maintenance windows.

Refurbished Quality and Warranty

This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished drives are a practical way to extend the lifecycle of existing HPE server and storage installations while controlling budget and reducing electronic waste.

All products from Direct Hardware Supply include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries: three-month warranty). Extended warranty options are available on request, and we ship worldwide from Denmark. If you need mounting parts for specific chassis generations, match the drive to the correct CADDY for your ProLiant SFF bay.
