Capacity and purpose

The Seagate ST4000NM0024 provides 4TB of storage on a 3.5" SATA 6.0Gb/s interface. It spins at 7200 RPM with a 128MB cache for fast sequential and random access. The drive is engineered for enterprise workloads of 550TB per year.

Build and connectors

The bare drive uses a standard SATA data and power connector layout compatible with desktop drive bays and hot-swap trays. Multi-drive firmware is optimised for RAID environments to maintain array availability. Rotational vibration safeguards help sustain performance in multi-bay chassis.

Thermals noise and power

The 7200 RPM spindle and enterprise-grade motor are rated for continuous 24x7 operation. Average latency is specified at 4.16ms. The design targets sustained throughput under heavy load rather than idle acoustics.

Questions about this item

What real-world throughput does the SATA 6.0Gb/s interface deliver on this drive?

The SATA 6.0Gb/s link caps at 6.0Gb/s; actual sustained rates depend on the 7200 RPM platters and 128MB cache.

Will the 3.5" form factor fit my standard desktop drive bay and SATA connectors?

Yes, the 3.5" form factor matches standard desktop bays and uses the same SATA data and power connectors.

How do I install the bare drive in a RAID array, and what firmware step is often missed?

Mount the drive in a 3.5" bay, connect SATA data and power cables, then ensure the RAID controller loads the enterprise firmware tuned for 550TB/yr workloads.
