HPE 861742-B21 4TB 7.2K-RPM SATA 6Gb/s LFF Hard Drive
The HPE 861742-B21 (Spare Part: 862140-001 / Assembly: 846520-002 / Model: MB6000GVYZB) is a genuine 4TB SATA Business Critical hard drive built for enterprise storage environments where cost-per-gigabyte and dependable performance are essential. Spinning at 7,200 RPM with a 600 MBps external data transfer rate, it's engineered to support server workloads, backup operations, and archival storage tiers with a balanced approach to speed and economy. The 6Gb/s SATA interface provides a stable, high-throughput connection, which is exactly what ProLiant Gen10 through Gen12 servers are built around.
What sets this drive apart is its 512e Advanced Format, ensuring compatibility with both legacy 512-byte and modern 4KiB-aligned operating systems and applications. The drive features Digitally Signed (DS) firmware, which provides the security and assurance that drive firmware comes from a trusted source and protects against malicious attacks. It also supports Instant Secure Erase (ISE) technology to simplify the cost and complexity of re-purposing or disposing of drives while protecting data. As a Business Critical (BC) drive, it offers enterprise-class reliability for 24/7 operation, yet remains more affordable than high-performance Enterprise models. It comes with an HPE Low Profile Carrier (LPc) pre-attached, featuring a genuine HPE serial number and security sticker, making it ready for hot-plug installation in compatible ProLiant systems.
All HPE hard drives pass a rigorous qualification process, which certifies that every drive is proven to perform in your HPE ProLiant Server environments. Before final certification, all HPE Server Midline Hard Drives are optimized for compatibility and functionality, including support of SMART and HPE Systems Insight Manager.
Because this is a genuine HPE component rather than a generic or rebadged drive, it carries original HPE firmware and a genuine HPE security sticker. That matters when you're replacing a drive in a live server — mismatched or unverified parts can cause RAID rebuild failures or degraded performance.
