HPE 861688-B21 3TB 7.2K-RPM SATA 6Gb/s LFF Hard Drive
The HPE 861688-B21 (Spare Part: 862131-001 / Assembly: 846522-003 / Model: MB3000GVYZH) is a genuine 3TB SATA Midline hard drive built for enterprise storage environments where cost-per-gigabyte and dependable performance are essential. Spinning at 7,200 RPM with a 128MB DDR4 cache buffer and an 8.5ms average seek time, 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 with a data transfer rate of 600 MBps, which is exactly what ProLiant Gen10 through Gen12 servers are built around.
What sets this drive apart is its Low Profile Carrier (LPc) design, which is specifically engineered for select HPE ProLiant SATA servers with 3.5-inch LPc drive bays, including Gen10, Gen10+, Gen11, and Gen12 platforms. The drive features 512e Advanced Format for improved data integrity and storage efficiency, as well as Digitally Signed (DS) firmware which prevents unauthorized access and protects against malicious attacks. As a Midline (MDL) drive, it offers an ideal balance between performance and cost — more robust than desktop drives with better reliability for 24/7 operation, yet more affordable than high-performance Enterprise models. It comes with an HPE Low Profile Carrier (LPc) pre-attached (as pictured), 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.
