Seagate Exos X18 18TB 512e/4Kn SATA III 6 Gb/s 3.5" Internal Hard Drive, Data Transfer Speeds Up to 270 MB/s, 7200 RPM Speed, 256MB Cache, Fast Format 2,500,000 Hours MTBF | ST18000NM000J

The Seagate Exos X18 (ST18000NM000J) is the cornerstone of Seagate’s enterprise storage portfolio. Optimized for large-capacity data transfers and low latency, it allows data centers to scale capacity effectively without increasing their footprint. This 18TB drive is specifically designed to meet the demands of public and private cloud storage, big data analytics, and high-capacity RAID systems.
 

Performance: 7200 RPM and Advanced Caching
Equipped with a 256MB cache and a 7200 RPM spindle speed, the Exos X18 delivers the responsive performance necessary for demanding enterprise environments. It utilizes advanced write caching and digital environmental sensors to ensure peak performance in even the most challenging multi-drive chassis. With sustained data rates reaching 270 MB/s, it excels at both sequential and random data processing.
 

Enterprise-Class Reliability: HelioSeal Technology
The Exos X18 features a helium-sealed drive design to reduce internal friction and turbulence. This not only improves mechanical reliability but also contributes to lower power consumption and weight. It boasts an industry-leading 2.5 million-hour MTBF and a workload rating of 550TB per year, ensuring it can withstand the constant read/write cycles of a 24/7 enterprise environment.

Advanced Security and Efficiency
Security is a top priority for enterprise data. The ST18000NM000J includes Seagate Secure technology for safe and easy drive retirement via Instant Secure Erase (ISE). Furthermore, PowerChoice™ and PowerBalance™ features allow administrators to optimize power consumption during idle periods and active use, significantly reducing the Total Cost of Ownership (TCO) across large-scale deployments.

Why the Exos X18 18TB Stands Out
Massive 18TB Capacity: Ideal for dense storage requirements and high-capacity server builds.

CMR Technology: Ensures predictable, high-speed performance for all enterprise workloads.

Helium-Sealed: Lowers power consumption and enhances long-term mechanical stability.

Versatile Formatting: Supports both 512e and 4Kn formats for broad compatibility with legacy and modern systems.
