HPE P52745-B21 2.5-Inch SAS Hard Drive
Overview
The HPE P52745-B21 is a 500GB 2.5-inch SAS hard drive rated for 7200 rpm operation with a 6 Gbps interface. This is a direct-replacement or spare storage component for HPE ProLiant servers and storage systems that require 2.5-inch form-factor drives. If you're expanding or replacing failed drives in a small-form-factor (SFF) server chassis — particularly DL320 G11 configurations or similar compact rack units — this drive provides the mechanical compatibility and interface speed needed without overspec-ing capacity.
Compatibility
Verify compatibility with your specific HPE ProLiant server model before ordering. The P52745-B21 is designed for HPE systems that support 2.5-inch SAS drives at 6 Gbps (SAS-2). Common compatible platforms include DL320 G10 and G11 generation servers, though your system documentation or parts list should confirm that this drive type is approved for your exact configuration. Do not assume compatibility across all HPE product lines — some storage systems use different form factors or require SAS-3 (12 Gbps) interfaces.
Installation Notes
This is a 2.5-inch drive: it will not fit 3.5-inch bays without an adapter bracket (not included). Ensure your chassis has available SAS ports or a backplane connection. Power the drive via the SAS backplane or direct SAS power connector — no separate SATA power is needed. Secure the drive in its bay using the mounting brackets or caddy supplied with your server; do not force it into place. The 1.10 lb weight is negligible for rack installation.
