HGST Ultrastar 7K4000 4TB SATA Drive

This 3.5-inch internal hard drive provides four terabytes of storage on a SATA 6Gb/s interface. It spins at 7200 RPM with a 64 MB buffer to sustain steady throughput for desktop workloads. The drive is supplied new in retail or OEM packaging.

Ideal for Bulk Storage and RAID Arrays

The drive suits builders who need high-capacity mechanical storage for media libraries, backups or RAID sets where cost per terabyte matters. It is not suited for users who require the low latency of solid-state storage or who need a 2.5-inch form factor for compact chassis.

SATA 6Gb/s Interface Determines Compatibility

The drive connects through a standard SATA 6Gb/s port and will operate at that link speed when the host controller supports it. Systems limited to SATA 3Gb/s will still work but at the lower interface rate.

Questions about this item

Will the 3.5 inch form factor and 5.8 inch depth fit my standard desktop drive bay?

Yes, the drive measures 3.5 inches wide and 5.8 inches deep, matching standard 3.5 inch internal bays.

Do I need a special bracket or cable to install the SATA 6Gb/s interface?

Connect the drive using a standard SATA data cable and a SATA power connector from your power supply; no special bracket is required for 3.5 inch bays.

How often should I check the 64MB buffer or mechanical parts for wear?

The 64MB buffer is solid-state and needs no maintenance; monitor SMART attributes for the 7200 RPM mechanical assembly and replace the drive if reallocated sectors appear.
