The Seagate ST16000NM000J is a 16TB internal hard drive from the Exos X18 enterprise storage family. Designed for data-center and enterprise storage environments, it combines high-capacity storage with a 7200RPM spindle speed, SATA 6Gb/s interface, and 256MB cache. Its helium-sealed construction and conventional magnetic recording (CMR) technology make it suitable for compatible servers, storage arrays, and large-capacity data repositories.
Product Overview
The Exos X18 family is engineered for enterprise workloads that require high-capacity storage and continuous operation. The ST16000NM000J is the standard SATA model with a 512e logical sector format and FastFormat support for compatible 512e or 4Kn configurations. It provides storage for business data, backup repositories, large datasets, and enterprise applications.
Key Features
- 16TB storage capacity: Provides substantial space for enterprise data, backups, and large datasets.
- 7200RPM spindle speed: Supports data access in compatible server and storage environments.
- SATA 6Gb/s interface: Connects to compatible SATA-equipped servers, storage enclosures, and workstations.
- 256MB cache: Helps manage data-access and transfer operations.
- Helium-sealed CMR design: Combines high-capacity drive construction with conventional magnetic recording for enterprise storage workloads.
Enterprise Storage Applications
- Enterprise servers and data-center storage
- Compatible RAID arrays and storage enclosures
- Business backup and archive repositories
- Cloud infrastructure and centralized data storage
- Data-intensive enterprise applications and analytics storage
Reliability and Storage Management
The Exos X18 family includes features such as Native Command Queuing (NCQ), SMART monitoring, and PowerChoice power-management technology. Seagate specifies a 2.5-million-hour MTBF and a 0.35% annualized failure rate for the applicable drive family under stated operating conditions. These are manufacturer reliability metrics, not a guarantee of an individual drive's lifespan.
Compatibility and Installation
The ST16000NM000J uses a standard 3.5-inch SATA connection. Before installation, verify that the server, RAID controller, host bus adapter, or storage enclosure supports 16TB drives and the required sector format. FastFormat conversion and full-capacity support depend on compatible host hardware, firmware, and configuration.
Standard Model Identification
The ST16000NM000J is the standard SATA model in the Exos X18 family. It should not be confused with ST16000NM001J, the SATA self-encrypting variant. Confirm the full model number when matching a replacement drive or selecting storage for a particular system.
DC Supplies Product Note
Before ordering the Seagate ST16000NM000J, confirm the exact model number, SATA interface, supported capacity, and sector-format requirements of your storage system. The advertised 16TB capacity uses decimal units, so the operating system may report a lower usable figure. RAID configuration, filesystem formatting, and system overhead can reduce available capacity further.
