Description
Sixth-Generation Enterprise Design
The Ultrastar 7K4000 is a robust, sixth-generation HGST 5-platter designed internal hard disk drive, specifically built and tested for enterprise-class applications where storage density, watt-per-gigabyte, and cost-per-gigabyte are critical parameters. It succeeds the Ultrastar 7K3000 with a 33% capacity increase at 24% lower watts per gigabyte — delivering more storage for less power in the same 3.5″ footprint.
Precision Engineering for Multi-Drive Environments
Beyond the standard DSA and RVS features carried over from the 7K3000, the 7K4000 adds Thermal Fly-height Control (TFC) with an internal thermal sensor to provide a better soft error rate for improved reliability and performance. This is particularly relevant in dense enclosures where temperature variations can affect read/write head positioning — a common source of soft errors in high-density RAID arrays.
Advanced Format & Compatibility
The Ultrastar 7K4000 is an Advanced Format drive, backwards compatible with legacy 512-byte sector size by offering built-in 512-byte emulation through the SATA III 6Gb/s interface. This means it slots into both modern and legacy server infrastructure without configuration headaches.
Power Efficiency
Five Advanced Power Management modes help reduce power consumption by up to 59% during low-RPM idle mode, with standby and sleep states pulling as low as 1W — making it well-suited for cold data storage, archiving, and replication environments where drives spend significant time idle.
💡 Offered as legacy stock, this drive represents exceptional value for businesses building out server, NAS, or RAID storage on a budget. The 7K4000’s enterprise pedigree and added Thermal Fly-height Control make it a step up from the 7K3000 for environments where thermal stability is a concern.
