HPE 870761-B21 900GB 15K-RPM SAS 12Gb/s LFF Hard Drive
The HPE 870761-B21 is a genuine 900GB 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 is 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 a data transfer rate of 1.2 GBps, ensuring your most demanding applications never wait for storage.
What sets this drive apart is its 512n Advanced Format, ensuring broad compatibility with legacy operating systems and applications. 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. Robust SAS interface with dual-port full-duplex connectivity provides built-in redundancy, boosting availability and fault tolerance in enterprise environments. As an Enterprise (ENT) class drive, it offers the highest level of performance and reliability for 24/7 data center operations. It comes with an HPE Low Profile Carrier (LP) pre-attached, featuring a genuine HPE serial number and security sticker, making it ready for hot-plug installation in compatible ProLiant systems.
All HPE hard drives pass a rigorous qualification process, which certifies that every drive is proven to perform in your HPE ProLiant Server environments. 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.
