Seagate Exos X24 ST16000NM002H 16TB 3.5-Inch Enterprise SATA Hard Drive

Product Overview

The Seagate Exos X24 (ST16000NM002H) is a high-performance enterprise-class 3.5-inch hard drive engineered for hyperscale data centres and mission-critical storage workloads. With a massive 16TB storage capacity and a SATA 6Gb/s interface, this drive delivers outstanding throughput, reliability, and energy efficiency for large-scale cloud infrastructure, enterprise servers, and high-density storage arrays.

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 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. Ideal for high-density deployments where capacity per rack is the primary constraint, it helps data centre architects scale storage without expanding physical infrastructure.

SATA 6Gb/s Interface with Up to 285 MB/s Transfer Rate

Equipped with a SATA III 6Gb/s interface, the drive achieves a maximum sustained data transfer rate of up to 285 MB/s, ensuring fast sequential read/write performance for large-scale data ingestion and retrieval. The large 512MB multisegmented cache with advanced write caching and full-track multiple-sector transfers further boosts throughput for data-intensive workloads.

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 delivers an additional layer of data integrity across large RAID arrays, while S.M.A.R.T. monitoring and on-the-fly error-correction algorithms ensure consistent, reliable performance.

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. A Fluid Dynamic Bearing motor further reduces acoustic output — 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 balance between performance and energy consumption, significantly reducing total cost of ownership (TCO) at scale across hyperscale and enterprise deployments.

Seagate Secure™ with Instant Secure Erase

The Exos X24 features Instant Secure Erase (ISE) for fast, compliant drive repurposing and disposal. Optional Self-Encrypting Drive (SED) and FIPS 140-3 validated models are available, providing government-grade data-at-rest protection and full compliance with corporate and federal security standards. Authenticated firmware downloads via RSA 3072 verification further protect drive integrity.

FastFormat™ Technology

Supporting both 512e and 4Kn sector formats, the Exos X24 includes Seagate's FastFormat™ feature, enabling easy reformatting between sector sizes without drive replacement — providing flexibility for evolving infrastructure requirements and compatibility with both legacy and modern systems.

Hot-Plug Support

With native hot-plug support, the Exos X24 can be inserted or removed from a live system without causing downtime, making it ideal for enterprise SATA storage arrays and high-availability server environments that require continuous, uninterrupted operation.
