Enterprise-grade 4 TB storage
The HGST Ultrastar 7K4000 is a 3.5-inch internal hard drive built for continuous operation in servers and storage arrays. Its 7200 RPM spindle and 64 MB cache serve workloads that demand sustained throughput rather than burst speed. The SATA 6.0Gb/s interface fits standard drive bays and controllers without extra adapters.
Capacity and sustained workloads
Four terabytes provide room for large media libraries, backup sets or archival datasets that grow steadily. The 2.0 million hour MTBF rating reflects design testing aimed at minimising downtime in multi-drive environments. Random I/O performance will limit responsiveness in heavy transactional databases or virtualisation clusters.
Included accessories and software impact
The drive ships in retail or OEM packaging that may vary; no mounting hardware, cables or management utilities are bundled. Installers must supply their own SATA data and power cables along with any tray or screws the chassis requires. Software-based RAID or monitoring tools are not included.

Questions about this item
Will the SATA 6.0Gb/s interface on this 4TB drive work with my older motherboard that only has SATA 3.0Gb/s ports?
Yes, the SATA 6.0Gb/s interface is backward compatible with SATA 3.0Gb/s ports, so the drive will function normally at the slower speed.
How can I verify the 7200 RPM spindle speed and 64MB cache are active after installation?
Check the drive model 0F14683 in your BIOS or use a tool like CrystalDiskInfo to confirm the reported rotation speed and cache size match the specifications.
Does the retail box include a SATA data cable and mounting screws for a 3.5" bay?
Packing may vary between retail and OEM versions; a SATA data cable and 3.5" mounting screws are often not included and may need to be purchased separately.
