Enterprise SAS drive for server arrays
The Seagate Constellation.2 ST9500620SS is a 500GB 2.5-inch hard drive built for enterprise server environments. It uses a SAS 6Gb/s interface and spins at 7200 RPM with a 64MB cache. The 15mm z-height fits standard 2.5-inch drive bays in rackmount chassis.
500GB capacity with 7200 RPM throughput
The 500GB capacity suits nearline workloads such as logging, backup staging or secondary application storage. Sequential throughput is adequate for batch jobs and archival reads. Random I/O will saturate the 4.16ms average latency under heavy concurrent request queues.
1.4M-hour MTBF and low idle power
Rated at 1.4M hours MTBF, the drive targets continuous operation in multi-drive arrays. Idle power stays under 3.27 watts, helping dense deployments stay within thermal budgets. The bare-drive package requires a SAS backplane or HBA with appropriate cabling; no tray or mounting screws are included.

Questions about this item
Will the SAS 6Gb/s interface work with my existing SAS backplane?
The drive uses a standard SAS 6Gb/s interface compatible with SAS backplanes and controllers that support 6Gb/s signalling.
How can I verify the drive is operating correctly after installation?
Check that the drive spins at 7200 RPM, reports 500GB capacity, and shows an average latency near 4.16ms in SMART or controller diagnostics.
Does the bare drive include a mounting tray or cables?
The 2.5 inch bare drive ships without a tray, cables, or screws; you must supply a compatible 15mm SAS tray and cabling for your chassis.
