HP 846996-B21 4TB 7.2K-RPM SAS 12Gb/s LFF Hard Drive
The HP 846996-B21 (Spare Part: 847035-001 / Assembly: 765252-001 / Model: MB4000JEFNC) is a genuine 4TB SAS 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 cache buffer and an average seek time of 7.6ms, it's engineered to support server workloads, backup operations, and archival storage tiers with a balanced approach to speed and economy. The 12Gb/s SAS interface provides a stable, high-throughput connection with a data transfer rate of 1,200 MBps, which is exactly what ProLiant servers and D6020/D6000 storage enclosures 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. 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. The drive features Secure Erase support for data security and comes with an HP Smart Carrier (SC) pre-attached, making it ready for hot-plug installation in compatible ProLiant systems.
Because this is a genuine HP component rather than a generic or rebadged drive, it carries original HP firmware and a genuine HP 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.
