Seagate Exos X18 16TB 3.5" 7200RPM SAS 12Gb/s HDD

The Seagate ST16000NM005J is an internal hard drive designed for enterprise environments that need dependable, high-capacity storage. With 16TB of space built on conventional magnetic recording, it gives administrators room for large data sets, virtual machine libraries, and long-term archives without expanding rack footprints.

Performance is anchored by a 7200 rpm spindle speed, a SAS 12Gb/s interface, and a 256MB buffer. Together these elements support sustained transfers up to 261 MB/s and deliver an average latency of 4.16 ms, so workloads such as analytics, content delivery, or backup rotations move quickly and predictably.

The helium-sealed build reduces internal friction and helps the drive achieve a 2,500,000-hour MTBF rating, which is critical for always-on deployments. Hot-plug support lets technicians replace or add drives without powering down a system, while hardware-based encryption with SED capability protects data at rest and simplifies compliance with security policies.

Use the drive in dense storage arrays, scale-out file systems, or high-throughput backup targets. Data centers, cloud providers, and enterprise IT teams that run demanding workloads will appreciate its balance of capacity, speed, and reliability.
