HPE 861752-B21 4TB 7.2K-RPM SATA 6Gb/s LFF Hard Drive
The HPE 861752-B21 (Model: MB004000GWFVQ / Spare: 862139-001) is a genuine 4TB 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 64MB cache buffer and a 7.45ms 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 MB/s, which is exactly what ProLiant Gen8, Gen9, and Gen10 servers are built around.
What sets this drive apart is its Digitally Signed (DS) firmware, which provides the security and assurance that drive firmware comes from a trusted source and protects against malicious attacks. As a Midline (MDL) drive with 512e Advanced Format, 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. The drive features Rotational Vibration Sensors for enhanced rotational vibration tolerance, delivering enterprise-class reliability. It comes with an HPE SmartDrive Carrier (SC) pre-attached (as pictured), making it ready for hot-plug installation in compatible ProLiant systems.
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.
