Seagate ST1800MM0158 1.8TB 10000RPM 2.5" SAS laptop hard drive

Enterprise Performance 10K HDD

The Seagate ST1800MM0158 is a 1.8TB 2.5-inch laptop internal hard drive spinning at 10000 RPM with a 128MB cache. It targets enterprise environments and write-intensive workloads that demand high-performance data access in a compact form factor. The SAS interface supports 12Gb/s connectivity for integration into compatible servers and storage arrays. This new drive suits IT professionals and system builders focused on transaction-heavy applications.

Sustained workload behaviour

TurboBoost enhanced cache option accelerates I/O operations to complete more transactions in less time during peak demand. Average latency of 2ms contributes to predictable response times when the drive operates under continuous load. Intelligent NAND management with TurboBoost provides enterprise-grade endurance for write-intensive use cases. The 12Gb/s SAS interface maintains consistent throughput without the variability seen in burst-only benchmarks.

Build quality and connectors

The 2.5-inch footprint allows dense deployment in space-constrained chassis while delivering 1.8TB capacity. SAS connectors ensure secure, locking connections suitable for vibration-prone rack environments. Self-Encrypting Drive models protect data at rest without relying on host software. Retail or OEM packing may vary, so mounting hardware and cables are not guaranteed in the box.
