HPE 872842-B21 300GB 15K-RPM SAS 12Gb/s SFF Hard Drive
The HPE 872842-B21 (Spare Part: 873035-001 / Model: EG000300JWFUQ) is a genuine 300GB SAS Enterprise hard drive built for enterprise storage environments where performance, uptime, and data integrity are absolutely critical. Spinning at an industry-leading 15,000 RPM with a 128MB cache buffer and an average seek time of just 2.72ms, it's engineered to deliver maximum IOPS and minimal latency for transaction processing, database workloads, and other mission-critical deployments where every millisecond matters. The 12Gb/s SAS interface provides the fastest possible throughput with a data transfer rate of 1.2 GBps, ensuring your most demanding applications never wait for storage.
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. The drive features dual-port SAS connectivity for built-in redundancy, boosting availability and fault tolerance in enterprise environments. It comes with an HPE SmartDrive Carrier (SC) pre-attached, featuring system status LEDs, a "Do-Not-Remove" button to prevent accidental drive removal, and a remote activation LED for streamlined maintenance in large server arrays. The 512n sector format ensures broad compatibility with legacy operating systems and applications.
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 production server — mismatched or unverified parts can cause RAID rebuild failures, performance degradation, or even system crashes.
