  • 2 TB capacity stores large datasets
  • 10000 RPM spindle speed accelerates data access
  • 12 Gbps SAS interface enables fast transfers
  • 128 MB cache buffers intensive workloads
  • Includes Gen 14 PowerEdge caddy for direct installation

1.2 TB 10K SAS drive for Dell PowerEdge

This 2.5 inch internal hard drive delivers 1.2 TB of storage at 10000 RPM with a 12 Gbps SAS interface. It includes a Gen14 PowerEdge caddy for direct installation in compatible Dell servers. The 128 MB buffer supports sustained throughput for transactional workloads.

12 Gbps SAS bandwidth and server backplane limits

The 12 Gbps SAS link provides the electrical ceiling for data transfer, but real-world throughput depends on the server backplane, controller firmware and cable quality. Multi-drive arrays share the same bus, so aggregate performance scales with the number of active spindles and the RAID level chosen. Hot-plug operations require a compatible backplane and controller support.

10000 RPM spindle speed defines latency profile

The 10000 RPM rotation rate sets the average rotational latency and random IOPS ceiling for this drive. Workloads needing lower latency or higher random performance will require solid-state media instead. Buyers who need larger capacity per bay or quieter operation for desktop use should consider alternative form factors.
