The HPE P28028-B21 is a genuine 300GB SAS Mission Critical hard drive built for the most demanding enterprise storage environments where performance, uptime, and data security are absolutely critical. Spinning at an industry-leading 15,000 RPM, 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 data transfer rates up to 1.2 GBps, ensuring your most demanding applications never wait for storage.
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 qualification programs. 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 comes with a Basic Carrier (BC) tray pre-attached, making it ready for hot-plug installation in compatible ProLiant Gen10 Plus, Gen11, and Gen12 servers. The 512n sector format with Instant Secure Erase (ISE) support 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.
This HPE P28028-B21 300GB SAS hard drive is built specifically for HPE's next-generation ProLiant server architecture with Basic Carrier (BC) compatibility. It is designed for Gen10 Plus, Gen11, and Gen12 server families with 2.5" SFF drive bays. Before ordering, it's worth double-checking your exact server model and backplane revision. In general, this drive fits into:
HPE ProLiant Gen10 Plus Servers:
HPE ProLiant Gen11 Servers:
HPE ProLiant Gen12 Servers:
HPE SimpliVity Systems:
