Seagate ST2000NX0273 2TB 7200RPM SAS Enterprise Hard Drive

Name: Seagate ST2000NX0273 2TB 7200RPM SAS Enterprise Hard Drive
Brand: Seagate
SKU: ST2000NX0273

Overview

The Seagate ST2000NX0273 is an enterprise-class 2.5-inch hard drive built for servers, storage arrays, and data center environments that demand consistent uptime and reliability. With a SAS 12Gb/s interface, it is designed to connect to enterprise-grade SAS controllers and host bus adapters rather than consumer SATA ports, ensuring compatibility with professional storage infrastructure. The 7200 RPM spindle speed paired with a generous 128MB cache delivers a maximum sustained transfer rate of 136 MB/s and an average latency of just 4.16ms, providing dependable throughput for transactional and sequential workloads.

The 2.5-inch small form factor is a key advantage for organizations building high-density storage solutions, allowing more drives per rack unit compared to 3.5-inch alternatives. At 2TB, the capacity suits applications like database storage, email servers, and surveillance systems where a balance of speed and storage space is needed. While SSDs have overtaken mechanical drives for latency-sensitive primary storage, the ST2000NX0273 continues to serve well in tiered storage architectures, RAID configurations, and scenarios where cost-per-gigabyte and proven mechanical reliability are priorities over raw IOPS performance.
