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.

商品問答

How much power does the 10000 RPM 2.5" SAS drive draw during continuous operation?

The 10000 RPM spindle speed and 128MB cache are designed for write-intensive workloads while keeping power draw low for data centre efficiency.

Does the 12Gb/s SAS interface need a specific controller or backplane to function?

The drive uses a 12Gb/s SAS interface so it requires a compatible SAS controller or backplane that supports this speed.

Can the ST1800MM0158 share a SAS backplane with older 6Gb/s SAS drives?

Yes, the 12Gb/s SAS interface is backward compatible and will negotiate down to 6Gb/s when paired with older drives on the same backplane.
