The HP 487442-001 (Compatible Part: AJ740A) is a genuine 1TB SATA Midline hard drive built specifically for HP MSA2 storage environments where cost-per-gigabyte and dependable performance are essential. Spinning at 7,200 RPM with a 32MB cache buffer, it's engineered to support server workloads, backup operations, and archival storage tiers with a balanced approach to speed and economy. The 3Gb/s SATA interface provides a stable, high-throughput connection with a data transfer rate of 300 MB/s, which is exactly what MSA2000 G1/G2 storage systems are built around.
What sets this drive apart is its proprietary MSA2 hot-plug tray that is different from standard ProLiant drives. HP MSA2 controller enclosures and large form factor expansion enclosures accept unique HP SAS disk drive modules with different firmware and different trays than other HP storage arrays and ProLiant servers. As a Midline (MDL) drive, it offers an ideal balance between performance and cost — more robust than desktop drives with better reliability for 24/7 operation, yet more affordable than high-performance Enterprise models.
Because this is a genuine HP component rather than a generic or rebadged drive, it carries original HP firmware and a genuine HP serial number. That matters when you're replacing a drive in a live MSA storage array — mismatched or unverified parts can cause RAID rebuild failures or degraded performance.
This HP 487442-001 1TB SATA hard drive is built specifically for HP MSA2 and MSA2000 storage architecture with a unique hot-plug tray that is different from standard ProLiant drives. It is designed for the following MSA storage systems. Before ordering, it's worth double-checking your exact array model and backplane revision.
