Enterprise Capacity Drive

The HGST Ultrastar 7K4000 is a 4TB 3.5-inch internal hard drive built for enterprise storage systems. It spins at 7200 RPM with a 64MB cache and carries a 2.0 million hour MTBF rating. The bare drive is designed for 24x7 operation in capacity-optimised applications.

SATA 6.0Gb/s Interface

This model uses a SATA 6.0Gb/s connection and supports both 512e and 512n sector formats for broad host compatibility. The 8ms average seek time and Dual Stage Actuator maintain consistent throughput in multi-drive chassis. No SAS variant is included in this specific SKU.

Bare Drive Packaging

The unit ships without cables, mounting brackets or management software. System integrators must supply their own SATA data and power leads along with any required drive trays. Retail or OEM packing may vary by supplier batch.

Questions about this item

What does the 7200 RPM spindle speed mean for actual throughput in a desktop system?

The 7200 RPM rotation enables sustained transfer rates suited to sequential workloads such as video editing or bulk file copies, while the 64 MB cache helps smooth burst I/O in everyday desktop use.

How does the SATA 6.0Gb/s interface limit real-world performance?

The SATA 6.0Gb/s link caps the drive at the interface's maximum signalling rate, so peak sequential reads and writes cannot exceed what the 6 Gb/s bus allows regardless of the 7200 RPM media speed.

Will the 26.10 mm height fit a standard 3.5-inch drive bay or hot-swap tray?

Yes, the 26.10 mm height matches the standard 3.5-inch form factor, so it mounts in any desktop bay, server chassis or hot-swap tray designed for 3.5-inch drives.
