16TB SATA drive for enterprise storage

The Seagate Exos X18 ST16000NM000J provides 16TB of capacity on a SATA 6.0Gb/s interface. It spins at 7200 RPM with a 256MB cache for high-throughput workloads. The 3.5-inch form factor fits standard enterprise bays. This drive is built for cloud data centres and massive scale-out deployments.

Sustained throughput for large data transfers

The hyperscale SATA model is tuned for large data transfers and low latency during continuous operation. Enhanced caching supports reliable performance under heavy, sustained workloads. Average latency is 4.16ms. PowerBalance technology optimises watts per terabyte across long duty cycles.

Helium-sealed design reduces power and heat

A helium sealed-drive design lowers power draw and weight compared to conventional air-filled drives. Digital environmental sensors monitor internal conditions for optimal operation. Proven side-sealing weld technology adds handling robustness and leak protection. The drive measures 26.1mm in height.

Questions about this item

How much power and heat does the 7200 RPM helium-sealed drive produce when running continuously?

The PowerBalance feature optimises watts per terabyte, and the helium sealed-drive design lowers power and weight for continuous operation in enterprise storage.

What host interface and cable does the SATA 6.0Gb/s 3.5" drive need to work?

It requires a SATA 6.0Gb/s port on the motherboard or controller, a SATA data cable and a standard SATA power connector from the power supply.

Will the 26.1 mm high 3.5" drive fit in the same bay and backplane as my older 3.5" SATA drives?

Yes, the 3.5" form factor with 26.1 mm maximum height matches standard 3.5" drive bays and SATA backplanes used by earlier SATA hard drives.
