About the Seagate Exos X16 12TB 7200RPM 3.5-inch SATA HDD
The Seagate Exos X16 12TB (ST12000NM001G) is a 3.5-inch enterprise-class hard drive engineered for demanding datacenter and hyperscale storage environments. Built on Seagate's proven perpendicular magnetic recording (PMR) technology with conventional magnetic recording (CMR), it operates at a sustained 7200 RPM spindle speed and delivers up to 261 MB/s sustained transfer rate, making it well-suited for high-throughput sequential workloads. The drive connects via a 6 Gb/s SATA III interface and features a 256 MB DRAM cache buffer to accelerate data staging and reduce latency under mixed workloads.
Designed to meet the rigorous demands of enterprise IT infrastructure, the Exos X16 12TB is rated for up to 550 TB per year workload rate — significantly higher than desktop or nearline consumer drives — and carries a 2.5 million hours MTBF rating. Advanced features including Seagate Secure hardware-based encryption (on select configurations), PowerChoice technology for configurable idle power states, and PowerBalance for optimizing the throughput-versus-power trade-off give datacenter operators granular control over energy consumption at scale. The drive also incorporates rotational vibration (RV) sensors to maintain performance integrity in high-density multi-drive enclosures.
The ST12000NM001G targets large-scale cloud storage, enterprise NAS arrays, object storage platforms, backup and archive repositories, and AI/ML data lake infrastructure where sustained throughput, high capacity density, and long-term reliability are critical operational requirements. Omnixon Global supplies this drive to enterprise and institutional buyers across the UAE, GCC, EMEA, and APAC regions, supporting large-volume procurement for datacenter build-outs and storage refresh projects.
Ideal for
- Hyperscale and colocation datacenter bulk storage arrays requiring high capacity density and sustained throughput
- Enterprise NAS and SAN deployments for file serving, data warehousing, and shared storage consolidation
- AI and machine learning data lake infrastructure where large sequential read workloads demand consistent MB/s performance
- Cloud object storage platforms (such as Ceph or MinIO clusters) needing cost-effective, high-capacity spinning media
- Backup, disaster recovery, and long-term archive systems with high annual workload requirements
- Surveillance and video analytics storage platforms ingesting continuous high-bitrate streams across multiple channels

Frequently Asked Questions about Seagate Exos X16 12TB 7200RPM 3.5-inch SATA HDD
What workloads is the Seagate Exos X16 12TB 7200RPM 3.5-inch SATA HDD designed for?
Enterprise mixed-use and read-intensive workloads — including transactional databases, AI inference data, virtualisation, hyperconverged storage, and analytics. Endurance is rated for sustained 24/7 operation, not consumer-style burst use.
Will this SSD work in my Dell / HPE / Lenovo server?
Most enterprise SSDs ship in vendor-branded variants tied to a server QVL. Share your server model and we will quote the correctly-branded SKU (Dell-genuine, HPE-genuine, Lenovo-genuine) so support and firmware update tooling work without complaints.
Do you provide support support locally?
Yes. All units are sourced through distribution, so support registers cleanly with the manufacturer (Samsung / Kioxia / Solidigm / Micron / WD / Seagate) and DOA replacement is handled through our Dubai operations within 5 business days for UAE/GCC.
How do I get a quote for a bulk order?
Use the RFQ form on this page with your quantity and destination. For larger and project-scale orders we engage the vendor directly to prepare a tailored quote, and our pre-sales team follows up with a vendor-confirmed quote.
