Seagate Exos X20z 20TB Enterprise Internal Hard Drive, ST20000NM001J

Seagate Exos X20z ST20000NM001J 20 TB Hard Drive - Internal - SATA (SATA/600) - Shingled Magnetic Recording (SMR) Method

Seagate Exos X20z ST20000NM001J enterprise hard drive delivers high-capacity storage for hyperscale cloud environments, data centers, and massive scale-out applications. With 20TB of storage, this internal drive helps organizations consolidate more data in fewer rack positions while supporting demanding workloads such as large-scale media storage, analytics, backup, and archival operations. Its host-managed shingled magnetic recording (SMR) technology enables high data density and is designed for compatible enterprise systems that support host-managed storage workflows.

High-Capacity Enterprise Storage
Built for hyperscale deployments, the Seagate Exos X20z combines high capacity with a 7,200 RPM spindle speed, enhanced caching, and a SATA/600 interface for efficient data transfers. The 256MB cache buffer helps support responsive access during burst workloads, while the SATA interface provides broad compatibility with enterprise storage platforms. Hot-pluggable operation supports convenient servicing and replacement in compatible data center systems.

Efficient, Durable Data Center Design
Seagate PowerBalance technology helps optimize power consumption per terabyte, while the helium-sealed enclosure reduces internal drag and supports lower power use and system weight. Next-generation helium side-sealing weld technology improves handling robustness and leak protection. Integrated environmental sensors monitor internal drive conditions to help maintain reliable operation, and Seagate Secure features support safe, efficient drive retirement and data protection practices.

Designed for continuous enterprise operation, the Exos X20z ST20000NM001J is backed by a 5-year limited warranty and a 2.5-million-hour MTBF rating. Its combination of capacity, performance, and data center-focused reliability makes it a strong choice for storage infrastructures that require dependable access to large volumes of information.
