HPE K2Q82A 4TB 7.2K-RPM SAS 12Gb/s LFF Hard Drive
The HPE K2Q82A (Spare Part: 801557-001 / Assembly: 807582-002 / Model: ST4000NM0034) is a genuine 4TB SAS Midline hard drive built specifically for HPE MSA2 storage environments where cost-per-gigabyte and dependable performance are essential. Spinning at 7,200 RPM with a 1.2 GBps external transfer rate, it's engineered to support data storage, backup, and mid-range workload applications with a balanced approach to speed and economy. The 12Gb/s SAS interface provides a stable, high-throughput connection, which is exactly what MSA storage arrays are built around.
What sets this drive apart is its unique MSA2 hot-plug tray with an interposer connector that is different from standard ProLiant drives. HPE MSA2 controller enclosures and large form factor expansion enclosures accept unique HPE SAS disk drive modules with different firmware and different trays than other HPE storage arrays and ProLiant servers. The disk drives have SAS interposers attached to the back which convert the native dual-port SAS interface to an SCA-40 connector — the interposer acts as a signal filter and port relocator to connect to the MSA2's proprietary backplane. The drive features dual-port SAS connectivity for built-in redundancy and is hot-swappable, meaning it can be replaced without shutting down the system — minimizing downtime during maintenance.
All HPE hard drives pass a rigorous qualification process, which certifies that every drive is proven to perform in your HPE storage environments. Before final certification, all HPE Server Midline hard drives are optimized for compatibility and functionality, including support of SMART and HPE Systems Insight Manager.
Because this is a genuine HPE component rather than a generic or rebadged drive, it carries original HPE MSA firmware and a genuine HPE serial number. That matters when you're replacing a drive in a live MSA storage array — mismatched or unverified parts can cause array dropouts or degraded performance.
