HGST Ultrastar 7K6000 4TB SATA Enterprise Drive

This 3.5 inch internal hard drive delivers 4TB of storage at 7200 RPM with a 128MB cache over a SATA 6.0Gb/s interface. It is built for enterprise storage workloads that demand consistent performance and high capacity in a standard form factor. The bare drive suits system integrators and IT professionals deploying RAID arrays, NAS appliances or backup servers.

7200 RPM Spindle 128MB Cache Thermal Profile

The 7th generation 5-disk design achieves best-in-class random and sequential performance with average seek time of 7.6ms and average latency of 4.16ms. Compared to the prior 7K4000 generation it offers 30% better power efficiency measured in Watts per TB. The 26.1mm height and 147mm length fit standard enterprise drive bays without special cooling requirements.

Upgrade From 7K4000 50% Capacity Gain

This model replaces the 7K4000 series with 50% more capacity at the same 4TB per drive density ceiling. The jump is worth it when you need higher areal density and improved power efficiency within existing 3.5 inch infrastructure. Buyers who need faster interface speeds or solid-state latency should evaluate different storage classes.

Questions about this item

How do I install the 3.5" SATA 6.0Gb/s drive in my desktop, and what step is often missed?

Mount the 147mm x 101.6mm drive in a 3.5" bay using four screws, connect the SATA data and power cables, then enable AHCI in BIOS so the 7200 RPM drive runs at full 6.0Gb/s speed.

What maintenance or replacement will the Ultrastar 7K6000 need later?

No routine maintenance is required; the sealed helium 5-disk mechanism and 128MB cache are designed for continuous enterprise workloads, so replacement only occurs if SMART attributes report reallocated sectors or bearing noise appears.

What limit appears first under sustained write loads on this 4TB enterprise drive?

The 7.6ms average seek time and 8ms average write latency become the bottleneck before the 6.0Gb/s SATA interface saturates, especially with random 512E sector workloads.
