Seagate Exos X24 ST16000NM007H 16TB 3.5-Inch Enterprise SAS Hard Drive

Product Overview

The Seagate Exos X24 (ST16000NM007H) is a next-generation enterprise-class 3.5-inch hard drive engineered for hyperscale data centres and mission-critical storage environments. With a massive 16TB storage capacity and a high-speed SAS 12Gb/s dual-port interface, this drive delivers superior throughput, path redundancy, and outstanding reliability for large-scale cloud infrastructure, enterprise SAN arrays, and high-density storage deployments.

Built on Seagate's globally proven Exos platform — deployed by leading cloud service providers worldwide — the X24 features a helium-sealed CMR design, a 512MB multisegmented cache, and a 2.5 million-hour MTBF, making it purpose-built for continuous 24/7 operation in the most demanding data centre environments.

Key Features

Massive 16TB Storage Capacity

The Exos X24 delivers 16TB of enterprise-grade storage per drive, maximising rack-space efficiency and enabling more petabytes per rack unit. This makes it an ideal choice for organisations scaling out cloud storage infrastructure or upgrading high-density RAID arrays where capacity per rack is the primary constraint.

SAS 12Gb/s Dual-Port Interface with Up to 285 MB/s Transfer Rate

Equipped with a SAS III 12Gb/s dual-port interface, the drive achieves a maximum sustained data transfer rate of up to 285 MB/s, delivering significantly higher bandwidth and lower latency compared to SATA-based drives. The dual-port design provides full path redundancy, making it essential for high-availability enterprise storage arrays and mission-critical SAN environments.

Enterprise-Grade Reliability

Rated for a workload of 550TB/year with a 2.5 million-hour MTBF and an annualised failure rate (AFR) of just 0.35%, the Exos X24 is engineered for uninterrupted non-stop operation. Super Parity technology provides an additional layer of data integrity across large RAID arrays, while T10 Protection Information and on-the-fly error-correction algorithms ensure consistent, reliable performance under heavy workloads.

Helium-Sealed CMR Design

The hermetically sealed helium-filled enclosure combined with Conventional Magnetic Recording (CMR) technology delivers high areal density, reduced power consumption, lower operating temperatures, and minimal vibration. This design ensures enhanced handling, robustness, and leak protection — all critical advantages in dense rack-mounted server environments running 24/7.

Advanced Power Management

Seagate's PowerBalance™ and PowerChoice™ idle power technologies allow IT administrators to fine-tune the balanc
