Deskstar 1 TB enterprise drive

The HGST Deskstar E7K1000 provides one terabyte of storage for enterprise and heavy-duty workloads. Its 7200 RPM spindle and 32 MB cache deliver consistent throughput for daily computing, NAS, RAID and CCTV DVR arrays. Rotational Vibration Safeguard technology maintains performance when multiple drives operate side by side. The drive targets a 1.2 million hour MTBF rating for extended service life.

Before installing check your system

Verify that your motherboard or controller offers a SATA 3.0 Gb/s port and that the operating system recognises 3.5 inch hard drives. Ensure the chassis has a standard 3.5 inch bay and that your power supply provides a SATA power connector for the drive. Confirm the BIOS or RAID controller supports the full 1 TB capacity without additional drivers.

Build quality and daily use

The bare-drive packaging omits cables and brackets so you must supply your own mounting screws and SATA data cable. RVS technology reduces vibration-induced errors in multi-drive enclosures, protecting data integrity during continuous operation. Balanced power management lowers thermal output, helping the drive run cooler in crowded server or NAS chassis. The SATA connector is compatible with existing SATA backplanes and hot-swap trays.

Questions about this item

Does the bare drive include cables or mounting hardware, or do I need to buy a SATA data cable and screws separately?

The drive is supplied as a bare unit only, so a SATA data cable and 3.5-inch mounting screws must be sourced separately.

I see the Deskstar E7K1000 name in the description — is that a different capacity or the same 1 TB model?

E7K1000 is the series name for this 1 TB, 7200 RPM, 32 MB cache drive; no other capacity is referenced.

How does the 1.2 million hour MTBF rating translate to everyday reliability in a desktop or NAS?

The 1.2 million hour MTBF is a design target for continuous operation, and the Rotational Vibration Safeguard helps maintain performance when multiple drives run together.
