The HP 846998-B21 (Model: MB6000JEFND / Spare: 847036-001 / Assembly: 765252-002) is a genuine 6TB SAS Midline hard drive built for enterprise storage environments where cost-per-gigabyte and dependable performance are essential. Based on Seagate Enterprise Capacity 3.5 HDD v4 (ST6000NM0034) technology, it spins at 7,200 RPM with a 256MB cache buffer and an 8.5ms average seek time, delivering high throughput for server workloads, backup operations, and archival storage tiers. The 12Gb/s SAS interface provides a stable, high-throughput connection with a data transfer rate of 1.2 GB/s, which is exactly what ProLiant Gen10 through Gen12 servers are built around.
What sets this drive apart is its 3.5" LFF Low Profile Carrier (LPc) design, which is specifically engineered for select HP ProLiant SAS 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 HP Low Profile Carrier (LPc) pre-attached (as pictured), 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.
This HP 846998-B21 6TB SAS hard drive is built specifically for HP's ProLiant server architecture with Low Profile Carrier (LPc) compatibility, which means it's designed to work within the storage enclosures and backplanes that were engineered to support SAS interfaces with LPc drive bays. It is designed for Gen10, Gen10+, Gen11, and Gen12 server families with 3.5" LFF LPc drive bays.
