Enterprise-class 3.5" drive with 3TB capacity, 7200 RPM and 64MB cache on SATA 6.0Gb/s
Options 3TB SATA 6.0Gb/s
The HGST Ultrastar 7K4000 is a 3TB 3.5-inch internal hard drive built for enterprise storage workloads. It operates at 7200 RPM with a 64MB cache and connects via a SATA 6.0Gb/s interface. The bare drive is rated at 2.0 million hours MTBF for continuous 24x7 accessibility.
The second-generation design delivers 24% lower W/GB than its predecessor, reducing power draw per unit of capacity during normal operation. Enterprise-class engineering targets consistent thermal performance in multi-drive environments. Acoustic output is managed for rackmount and server deployments where many units run simultaneously.
The 3TB capacity determines whether this drive matches the storage budget of the array or backup target you are planning. Optional Bulk Data Encryption on the SATA model adds a security layer for sensitive datasets. Buyers who need more storage per bay must select a higher-capacity model.

Mount the 3.5-inch bare drive using four screws in a standard bay, connect the SATA 6.0Gb/s data cable and a SATA power connector from the PSU, then enable the port in BIOS — the step many skip is confirming the SATA controller mode (AHCI) before the OS loads.
No routine maintenance is required; the sealed helium-free mechanism has no user-serviceable parts. Plan replacement when SMART attributes such as reallocated sectors or pending sectors rise, or after the 2.0 million-hour MTBF design life is approached in 24x7 operation.
The 6.0Gb/s SATA interface caps the maximum burst rate; under continuous write workloads the 7200 RPM platters and 64MB cache typically settle at the drive’s native sustained transfer speed, so the mechanical media limit is reached before the interface saturates.
