Capacity and Purpose
The Seagate Exos X18 ST16000NM001J is a 16 TB hard drive built for continuous operation in video surveillance systems and storage arrays. Its 7200 RPM spindle and 256 MB buffer serve workloads that write large sequential streams around the clock.
Build Integration
The 3.5 inch form factor fits standard drive bays and the SATA 6.0Gb/s interface connects directly to motherboard or controller ports without extra adapters. Hot-plug support lets administrators swap drives while the system stays online, reducing downtime in multi-bay enclosures.
Sustained Load Behaviour
A 7200 RPM spindle combined with a 256 MB cache maintains steady throughput during long recording or archival sessions. The 512e/4Kn disk format preserves compatibility with existing storage controllers while supporting modern sector addressing for large volumes.

Questions about this item
What is the spindle speed that defines the sustained throughput ceiling of the ST16000NM001J?
The spindle speed is 7200 RPM, which sets the mechanical limit for sustained data transfer on this 16 TB drive.
Does the 3.5 inch Exos X18 support hot-plug operation so it can be swapped without shutting down a storage system?
Yes, the drive is hot-pluggable, allowing removal or insertion while the host system remains powered on.
Which host interface must the system provide for this 16 TB model to function?
The drive requires a SATA 6.0Gb/s port, also labelled SATA/600, on the motherboard or controller.
