As the flagship of the Seagate X class, the Exos X16 enterprise hard drives are the highest-capacity drives in the fleet at the time of their release, and the ST14000NM001G brings that capability to any system with a standard SATA 6Gb/s port. No SAS HBA required — this drive slots directly into desktop motherboards, consumer NAS enclosures, and server platforms alike, making it a uniquely accessible enterprise drive for SMB and prosumer deployments.

Helium Sealed Design

The helium sealed-drive design delivers a lower total cost of ownership through lower power and weight, with next-generation helium side-sealing weld technology for added handling robustness and leak protection, and digital environmental sensors to monitor internal drive conditions for optimal operation and performance. Helium’s lower density compared to air reduces drag on the spinning platters, enabling more platters per drive, lower operating temperatures, and quieter operation — all critical factors at 14TB capacity.

PowerChoice & PowerBalance Technology

The Exos X16 features PowerChoice idle power technology and PowerBalance power/performance technology, enabling intelligent power management across multiple idle states without sacrificing response time when the drive is called back into active use. Combined with SuperParity data protection, the X16 is engineered for both efficiency and data integrity across extended deployment periods.

FastFormat & Flexible Sector Support

The ST14000NM001G supports both 512e and 4Kn sector formats via Seagate’s FastFormat technology, allowing field-switching between sector sizes to accommodate both legacy and modern storage infrastructure without replacing the drive.

Advanced Security

Seagate Secure features provide safe, affordable, fast, and easy drive retirement — with optional SED and FIPS models available across the X16 lineup for deployments with data-at-rest compliance requirements.
