4TB 7200 RPM desktop drive
The HGST Deskstar 7K4000 is a 3.5 inch internal hard drive with 4TB capacity and a 7200 RPM spindle speed. It connects through a SATA 6.0Gb/s interface and includes a 64MB buffer. The drive is supplied new and designed for standard desktop bays.
Who this suits and who should look elsewhere
This drive suits desktop builders who need high-capacity mechanical storage for bulk data, media libraries or backups. It is not for systems that require solid-state speed, low power draw or a 2.5 inch form factor. Buyers who need more storage than 4TB or a different interface should consider other options.
The deciding specification
The SATA 6.0Gb/s interface determines whether this drive will work in your system. Verify that your motherboard or controller provides a compatible SATA port before purchase.

Questions about this item
What does the SATA 6.0 Gb/s interface cap in practice?
The SATA 6.0 Gb/s interface caps the maximum data transfer rate at 600 MB/s, so the 7200 RPM drive cannot exceed that throughput even if its internal media speed is higher.
What physical space does this 3.5" drive need to fit or mount?
It requires a standard 3.5-inch internal drive bay and uses the usual SATA data and power connectors; the 4 TB capacity does not change the mounting dimensions.
How is this drive installed, and what step do people often get wrong?
Mount the drive in a 3.5" bay, connect the SATA data cable to a SATA 6.0 Gb/s port and attach the SATA power cable; the step often missed is enabling the SATA controller in BIOS so the 4 TB volume appears.
