Seagate ST1200MM0088 1.2TB 10K SAS 2.5" Hard Drive

Name: Seagate ST1200MM0088 1.2TB 10K SAS 2.5" Hard Drive
Brand: Seagate
SKU: ST1200MM0088

Overview

The Seagate ST1200MM0088 is a 1.2TB enterprise-class hard drive engineered for servers, storage arrays, and data center environments that demand reliable, high-speed mechanical storage. Its 10,000 RPM spindle speed significantly reduces rotational latency compared to standard 7,200 RPM drives, resulting in faster random read and write performance — a critical advantage for database workloads, virtual machine hosting, and transactional applications. The 12Gb/s SAS interface doubles the bandwidth of older 6Gb/s SAS connections while remaining backward compatible with legacy controllers.

Housed in a standard 2.5-inch small form factor enclosure, the ST1200MM0088 is designed to maximize drive density in rack-mounted servers and SAN enclosures. It is built for 24/7 continuous operation and is commonly deployed in RAID configurations where its consistent performance and enterprise-grade reliability help maintain uptime under sustained workloads. While enterprise SSDs have taken over many use cases, 10K SAS drives like this one remain relevant for environments where cost-per-gigabyte, proven reliability, and compatibility with existing SAS infrastructure are primary considerations.

Frequently Asked Questions

Can I use the Seagate ST1200MM0088 in a desktop PC or laptop?

No, this drive uses a 12Gb/s SAS interface, which requires a SAS controller or server backplane. It is not compatible with standard SATA connections found in consumer desktops and laptops.

What is the spindle speed and how does it affect performance?

The ST1200MM0088 spins at 10,000 RPM, which provides faster data access and lower latency compared to standard 7,200 RPM drives, making it well-suited for transaction-heavy enterprise workloads.

Is this drive compatible with SAS-2 (6Gb/s) controllers?

Yes, the 12Gb/s SAS interface is backward compatible with 6Gb/s SAS controllers, though throughput will be limited to the lower speed of the controller.

What type of servers or enclosures does this drive fit?

The ST1200MM0088 uses a standard 2.5-inch (SFF) form factor and fits in server drive bays and storage enclosures that accept 2.5-inch SAS drives.

Is this drive suitable for RAID configurations?

Yes, enterprise SAS drives like the ST1200MM0088 are designed for continuous operation and are commonly deployed in RAID arrays for redundancy and performance.
