The HPE 480942-001 (Option Part AJ740A) is a genuine 1TB SATA Midline hard drive built specifically for HPE MSA2 and MSA2000 storage environments where high capacity and dependable data access matter most. Spinning at 7,200 RPM with an 8MB cache buffer and an average seek time of 9ms, it's engineered to support server workloads, backup operations, and archival storage tiers with a balanced approach to speed and economy. The 6Gb/s SATA interface provides a stable, high-throughput connection with a data transfer rate of 300 MB/s, which is exactly what HPE StorageWorks MSA2 systems and ProLiant G5-G10 servers are built around.
This MSA2 drive features dual-port SATA connectivity for built-in redundancy, boosting availability and fault tolerance in enterprise storage environments. It is also hot-swappable, meaning it can be replaced without shutting down the system — minimizing downtime during maintenance. The drive comes with a unique MSA2/MSA2000 drive tray (as pictured), which uses different firmware and trays than other HP storage arrays and ProLiant servers. 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 storage array — mismatched or unverified parts can cause RAID rebuild failures or degraded performance.
This HPE 480942-001 1TB SATA hard drive is built specifically for HPE MSA2/MSA2000 storage architecture, which means it's designed to work within the storage enclosures and backplanes that were engineered to support SATA interfaces with unique MSA2 firmware and trays that are different from standard ProLiant drives. Before ordering, it's worth double-checking your exact system model and backplane revision, since storage systems can vary in supported drive firmware across generations. In general, this drive fits into:
HPE StorageWorks MSA2/MSA2000 Systems:
HPE ProLiant Servers (LFF Bays):
Compatibility Notes:
When you're sourcing a replacement drive for an active MSA2 storage array or ProLiant server, the difference between a genuine part and an unverified clone shows up the first time you need to rebuild a RAID set. The HPE 480942-001 is HPE-manufactured with a genuine HPE security sticker and original MSA2 firmware. This means it carries the firmware and mechanical tolerances your controller already expects — no compatibility guesswork, no risk of a failed rebuild because of a mismatched drive. Here's what makes this HPE 480942-001 1TB SATA hard drive worth choosing over a cheaper, unverified alternative:
This HPE 480942-001 1TB SATA hard drive fits teams maintaining MSA2 storage and ProLiant server infrastructure who need dependable, cost-effective storage without downtime. Common deployment scenarios include:
We are a trusted provider of genuine enterprise storage solutions including the HPE 480942-001 1TB SATA hard drive, with a focus on quality, compatibility, and customer satisfaction.
The HPE 480942-001 carries MSA2-optimized firmware and uses a proprietary drive tray that is unique to MSA2/MSA2000 storage systems. Generic SATA drives or drives intended for ProLiant servers lack this specialized firmware and tray design, which can lead to array dropouts, rebuild failures, or degraded performance. Choosing this genuine HPE MSA2 drive eliminates compatibility risks and keeps your SAN running reliably.
Yes, this drive is compatible with ProLiant Gen8 and Gen9 servers, as well as G5-G7 servers. However, if you're using it in a ProLiant server, you may need to use a standard hot-plug carrier instead of the MSA2 tray. Our free compatibility check confirms your specific server model and configuration before you order.
AJ740A is the HPE option (ordering) part number used for new system configurations, while 480942-001 is the spare part number used for service and replacement orders. They refer to the same 1TB SATA drive with identical specifications, dual-port design, and MSA2 firmware — you're getting the same genuine HPE quality either way.
