HDD HPE 4TB 3.5 inch SAS 7200 RPM 818367-B21

The HPE 4TB 3.5" 12G SAS internal hard drive (MPN 818367-B21) is a 3.5-inch enterprise-class SAS disk with 4 TB capacity and a 7200 RPM rotational speed. Engineered for servers and storage enclosures, it uses the SAS interface to provide high availability, data integrity and reliable performance for both mission-critical and storage-driven applications. The drive is available in HPE Smart Carrier, HPE Standard Hot Plug Carrier and HPE Non-hot Plug Carrier formats and supports 512e Advanced Format for 4KiB-aligned operating systems while maintaining compatibility with legacy 512-byte applications.

Advantages

The HPE 4TB SAS drive delivers robust, dual-port full-duplex SAS connectivity for increased throughput and redundancy, and is designed to meet enterprise reliability and availability requirements. It supports HPE Smart Carrier compatibility with ProLiant Gen8/Gen9 systems while remaining backward compatible with standard hot-plug carriers for older ProLiant G7 and earlier servers. The 7200 RPM speed and enterprise-grade construction make it suitable for sustained workloads and mixed application environments.
