HPE P40430-B21 300GB 10K-RPM SAS 12Gb/s SFF Hard Drive
The HPE P40430-B21 (Spare Part: P40785-001 / Assembly: P40754-001 / Model: EG000300JWEBF) is a genuine 300GB SAS Mission Critical hard drive built for enterprise storage environments where performance, uptime, and data integrity are absolutely critical. Spinning at 10,000 RPM with an external data transfer rate of 1.2 GBps, it's engineered to deliver high IOPS and low latency for transaction processing, database workloads, and virtualized environments where every millisecond matters. The 12Gb/s SAS interface provides a stable, high-throughput connection, which is exactly what ProLiant Gen10 Plus, Gen11, and Gen12 servers are built around.
What sets this drive apart is its Mission Critical (MC) classification — HPE's highest tier of enterprise storage designed for 24/7 operation with rigorous testing backed by over 3.35 million hours of the industry's most rigorous qualification program. The drive features Digitally Signed (DS) firmware, which provides the security and assurance that drive firmware comes from a trusted source and protects against malicious attacks. It also features 512n sector format for broad compatibility with legacy operating systems and applications. The drive comes with an HPE Basic Carrier (BC) tray pre-attached, 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 production server — mismatched or unverified parts can cause RAID rebuild failures, performance degradation, or even system crashes.
