Seagate Exos X16 12TB 3.5" 7200RPM SAS 12Gb/s Enterprise HDD

Overview

The Seagate ST12000NM004G is a 12 TB enterprise hard drive designed for 3.5-inch bays in servers and storage arrays. It operates at 7200 RPM and connects via a SAS 12 Gb/s interface, enabling high-speed data transfer and efficient multi-drive configurations. With a sustained transfer rate of up to 245 MB/s and a 256 MB cache, this drive handles large data workloads and random traffic bursts with consistent performance.

Its helium-sealed design reduces internal friction, lowering power consumption and heat generation, which is critical for continuous operation in data centers. Digital environmental sensors provide real-time monitoring of temperature and other conditions, while hot plug support allows for drive replacement without downtime, making it well suited for high-availability environments.
