Seagate NAS HDD 4TB SATA 6.0Gb/s

The Seagate NAS HDD ST4000VN000 is a 4TB 3.5-inch internal hard drive built for 1- to 8-bay NAS systems. It runs at 5900 RPM with a 64MB cache and a SATA 6.0Gb/s interface. The drive is designed for 24 x 7 operation in multi-bay enclosures.

Installation and common issues

The bare drive mounts in any standard 3.5-inch bay using four screws and connects with a SATA data and power cable. No special drivers are required; the drive appears in the NAS firmware after a reboot. The most common issue is forgetting to initialise the volume in the NAS operating system before use.

Pre-order checks

Verify that your NAS chassis has a free 3.5-inch bay and that the SATA backplane supports 6.0Gb/s speeds. Confirm the power supply can deliver enough current for an additional 3.5-inch mechanical drive. Ensure the NAS firmware is current so it recognises the full 4TB capacity.

Questions about this item

How can I verify the ST4000VN000 is running correctly after installing it in my NAS?

Check the NAS dashboard for drive detection, SMART status showing healthy, and the capacity reading 4TB with the 64MB cache recognised.

What ships with the bare-drive ST4000VN000 and what must I source separately?

Only the 3.5-inch drive arrives; you need to supply SATA data and power cables plus any mounting screws or trays your NAS requires.

Which capacity version of the Seagate NAS HDD series should I choose for a 4-bay enclosure?

The ST4000VN000 is the 4TB model; pick it when you want 4TB per bay, or select a different capacity from the same series if your storage plan differs.
